12x - ax = by - 8y
x(12-a) = by - 8y
x = (by - 8y)/(12-a)

12x + 8y = ax + by
You are solving for x which means to get x by itself on one side of the equation.
12x = ax + by - 8y
12x - ax = by - 8y
x(12 - a) = y(b - 8)
x = [y(b - 8)] / (12 - a)

12x+8y=ax+by
move all x terms to one side and all other to the other side
12x - ax = by - 8y
isolate x
(12-a)x = y(b-8)
divide by (12-a) to solve x
x = y(b-8)/(12-a)

12x+8y=ax+by solve for x
orx(12-a)=y(b-8).
x=y(b-8/(12-a).answer

subtract 8y and subtract ax from both sides
(12-a)x = (b-8)y
divide by 12-a
x = (b-8)y/(12-a)
