Your question is in the wrong category.
R is the unknown you are solving for
R+6=3
R+6-6=3-6
R+0=-3
R=-3

Can I solve 3x^3 -2x^2+5x=7
5x^3-4x^2+4x=6
4x^3-3x^2+6x=8
These equations by using Casio fx-82ES PLUS Calculator?????

Do you really need a calculator to solve a linear equation?
Let us see how to solve it without a calculator.
Remove the parentheses fronm the second term on the left : y-3
Use the distributive property on the last term on the right side -2y-6
Take the term -3 to the right side, changing its sign in the process (becomes +3)
Take the -2y term to the left making it +2y.
3y +2y=18+3-6 or 5y=15 and the answer is straightforward .

As to your Casio FX300ES, it cannot solve equations because it does not have an EQUATION calculation mode. The Casios FX-115ES and FX-991ES have an Equation Mode. If you use any of the two to solve an equation in one variable (linear, quadratic or other) the unknown is taken to be x by default. You would have to change the name of the variable from y to x.

y = x -3
This is a linear problem- so the usual way to solve the graph would be to solve where x = 0 and y= 0
if you use the format y = slope (m) * x + y intercept (b)- you would set y = 0
at that point it would be 0 = x -3 x = 3 Therefore where y = 0, x = 3. In a graph, that would point to the coordinate (3,0) for the x-intercept. To find the y-intercept, you'd set x = 0 at that point, you'd have the y-intercept being (0,-3)
so if y = 1, x would be 4; if y = 2, x = 5, and so on

There are a lot of ways to do it. One is to write a program using the cubic formula. If you just want the roots, use the solve() or zeros() functions.

For example, to find the zeros of x^2-6x^2+11x-6, enter
solve(x^3-6*x^2+11*x-6=0,x)
or
zeros(x^3-6*x^2+11*x-6,x)

Note that solve() has "=0" in it while zeros() does not.

solve() will give you an answer of
x=1 or x=2 or x=3
while zeros will give you an answer of
{1 2 3}
which plainly are the same thing, just expressed differently.

pls solve this prblm

explain to solve if 5+3+2=151022,9+2+4=183652,8+6+3=482466,5+4+5=202541,then what is 7+2+5=?

3(8)+3(5+3)=x(10+2) First add numbers in ()
3(8)+3(8)=x(12) Now multiply the numbers next to ()
24+24=12x Now add the 24 +24
48=12x Now we have to solve for x. 12x is actually 12 times x. in order to solve for x we have to do the opposite and divide by 12
48=12x
12 12

4=1x is the same as 4=x.

Hi,
You can use algebra to solve it.
Use the fact that 4 =2^2 and 8=2^3 and substitute in the equation
(2^3)^x =2^(3*x)
Then 2^(3*x)=2^2
By equating the exponents
3x=2 and x=2/3

Using the solve( function
With the calculator physical keys between square brackets, and the SHIFTed or ALPHA keys between parentheses, type in the following
8 [^ ] [ALPHA] [ ) ] (X) [ALPHA][CALC] ( =) 4 [SHIFT][CALC] (SOLVE)

Once the foregoing command entered press [=]
Display shows Solve for X on top line and probably 0.000 on bottom line.
Press [.] 5 to give 0.5 as a guess for the value of x
After a moment the calculator returns with the solution.
The display shows three lines
1st Line: 8[^] X =4
2nd Line: X= 0.66666666
3rd Line : L-R =0.

Your solution is 0.6666666. In fact the exact solution is 2/3.

Hope it helps.
