5I+5(I-31)=55 how do i solve this


Start by using the distributive property to expand the term 5(I-31)=5*I-5*31=5*I-155.
Rewrite the equation as 5*I+5*I-155=55
Combine the terms with I, this yields 10*I-155=55
Add 155 to both sides of the equation 10*I-155+155=55+155
you now get 10*I=210
Divide both sides of the equation by 10
(10*I)/10=210/10
Cancel the 10's on the left and divide 210 by 10 to get 21
Thus I=21

Basically you use the priority order of operations BEDMAS backwards

On the TI83 calculator the equation solver dont workequation solver dont work


Most probable that you are not using the correct syntax.
Press MATH, then scroll down to reach the SOLVER line. Press ENTER. Create the equation, using the ALPHA keyboard to type in letter symbols.
Press ENTER. The screen that opens displays the equation and a list of the variable present in your equation. Each letter (variable) must have a value, except the unknown. If there is a 0 after the = sign on the same line as the unknown, you must clear it so as to leave a blank.
Specify the lower bound and the upper bound to speed up the search.
Once finished press [ALPHA][ENTER] to execute the (SOLVER)

Im trying to create a program to run the colebrook formula but after i program it and enter the unknown i get error data type and brought back to program editor screen.


The error data type means that the program is expecting a specific type of data ( number, list, matrix, real, complex, string, etc.) while you are feeding it some other type of data. The point in the program where you are taken when the error occurs is where the exception was launched.

A common source of error stems from the use of variables that are global and defined in some other program. You can use the same name inside your program as long as you declare the variable local.
If your program is in fact a function, then all its argument must be passed in the call to the function: You cannot ask a function to read your input.

I will not pretend to know why you get the error, but the few comments I made above may help you debug the program.

By the way, if you are interested a Cobebrook online calculator, here is a link

This calculator model ti 85 can to searching equations of cubics?


There is nothing for directly solving cubics, but the general purpose Solver() function can be used for this. For example, given the cubic x^3+x^2=125 with a guess at a root at 4, Solver(x^3+x^2=125,x,4) will produce an answer of about 4.64. Full details are in the manual in the "Equation Solving" chapter.

Multiple equation solver


There are a few routines to solve simultaneous LINEAR equations that are embedded in the Operating system of the calculator.
  1. solve(
  2. Simult(
However if you are looking for the simultaneous equation solver application, you can download it from the TI website. Here is the link

If you need download and install instructions, you will find them here.

SC-6103 aurex prestige calculator


You must have pressed the MODE key followed by SOLV , QUAD or SIMUL-2 or SIMUL-3 . If the calculator has these a programs they solve a Quadratic equation, a simultaneous system of two linear equations (SIMUL-2) . a system of 3 linear equations (SIMUL-3).

To use these solvers (IF YOU ARE INTERESTED), you select the solver you want and you will be prompted for a first coefficient (a, or a1). You enter the value and press the DATA key and you will be prompted for the next coefficient.

To exit the Solver mode press the MODE key followed by the key next to which there is DEC or >DEC. It might also be marked COMP.
Sorry, I do not have that very calculator but an other AUREX Scientific calculator (DS-752C).

Hp48gx four pin connector is loose. Any way to fix it?


The only way is to open the calc seperate the main circuit and sodered the pins back
its a bit complicate because when you seperate the main circuit you also seperate the lcs and it need to go back to the same place otherwise you will have a missing lines on the screen

Will not print equations from word 2007. I teach math and I have the expanded format equation writer MATHTYPE. The printer does not print the equations correctly.


The problem may be the printer driver. When the printer was installed, it most likely defaulted to the HP PCL driver and your program may be wanting to use Postscript.

If your operating system is XP or Vista, both PCL and Postscript drivers are included. Simply go into the "Add Printer" wizard and install the printer again using the Postscript driver. Then try your MATHTYPE program and see if the equations print correctly. If not, you probably need to talk to whoever wrote the program to see if there are program specific drivers for their software, or if only certain printers are supported.

Solver mode in equations part of calculator


Your Solver is a numerical solver not a symbolic one. You have to supply an initial guess at a solution and the Solver finds it. If you suspect, or know, that there are others jut run the solver again supplying the initial guess for each additional solution.
One easy way to locate the roots of an equation is to draw the function (without =0) and see on the graph the approximate values of x where the function vanishes. These approximate values of the roots can be used as initial guesses in the Solver.
