Hi,
I assume that if you want to enter this equation in the calculator it is for the purpose of solving it for X. In other words you want to use the solve( function. There is no other purpose because it will be erased when calculator is turned OFF.
Here is how you use it.
Use the ALPHA key to enter X, Y, A,B,C,D, = (different from the normal =, which tells calculator to give the result)
When a solution is found the screen displays on 3 lines
The equation you entered : Y=
The value of X : X=
L-R (left member - right member) = 0 or a very small number.
For your particular example you enter 4(5x+3)=2(7x+6) as
4*(5* [ALPHA] X +3) [ALPHA][CALC] (=) 2*(7*[ALPHA] X + 6).
The [ALPHA][CALC] (=) is the = sign on the top left corner of the calculator, under (below) the [SHIFT key.
If you press [SHIFT]CALC] (SOLVE) just after entering the function, you will be asked a question Solve for X You will not be prompted for anything because all you coefficients are numbers. The equation will remain in memory until you turn calculator OFF.
Hope it helps.
Thank you for using FixYa and for rating this solution.

Refer to page 12 of the manual under Inputting expressions and values. It is pretty straight forward if you need further assistance please let me know.
Thank you,
Lee
it would be page e-10 if your going by the manual numbering.
Thanks,

I'm sorry what symbol are you referring to? do you know the name of the math you are trying to do? This may help me solve your problem quicker.
Thanks,

Sorry I am much more familiar with TI calculators.
You should be able to use your calculator to check the solution, as follows:
Most calculators have the ability to store a number in memory. You may
need to ask your teacher or read the instruction manual to learn how to do
this.
For example, on the TI-83 calculator, you would compute the number, press
the STO. key, press the X,T,,n key, and then press the ENTER key.
To recall the stored number, press the X,T,,n key.
Calculate the number 8
15 , and store it in x .
Calculate the left side of the original equation, using your stored number
x : 2x 3 + x . You should get 1:4.
Calculate the right side of the original equation, using your stored number
x : 5 4x 8x . You should get 1:4.
If the left and right sides of the equation give the same result, then your
solution is correct!
Hope this helps.
Thanks,
Lee

When I printed the manual page 12 shows correcting an expression. I went to the section varibles and varible overview and tried entering the equation as was not sucessful.
How do you put the (--) symbol in? When I add it in the equation and press =, I get an error message.
