Linear equation solver

It can solve linear equations in the format of

y = mx + c

where we are trying to find x and all of the other unknowns are given. For example I might input the equation -

9 = 2x + 1

This will then return the output of x = 4

this also produces fractional outputs if need be and negative outputs, for example:

-7 = 5x - 1

For which it will output x = -6/5 (CORRECT ANSWER)

This works for 8 bits on all 3 inputs (meaning your maximum input is 255 for y, m and c)

in its default state where all inputs are 0 the output will be 255 (because the computer thinks that 0 can fit infinitely many times into any number and since the largest output is 255 that's what it will say
