Question about Casio FX-115ES Scientific Calculator
I cant figure out how to put a linear equation in ex -7-3y= 11 solve for y
Rename your variable (unknown) X, because the calculator takes X as the default unknown. It will ask you "Solve for X?"
the 7, the second minus sign, 3 and 11 use the relevant keys.
For the first minus sign use the negation key or change sign (-)
For the variable X, examine the calculator keys on the row where the parentheses are. To the right corner of the key area there is a symbol in the same color as the ALPHA key. I believe the X is under the right parenthesis, or thereby.
To enter the X variable you press [ALPHA][ )]. To enter the = sign, you press [ALPHA] [CALC].
To execute the solve command, press [SHIFT] [CALC] and you will be prompted " Solve for X?"
