First
y(x + -3) = 4y + -12\
Then you would Reorder the terms:
y(-3 + x) = 4y + -12 (-3 * y + x * y) = 4y + -12
And theses (xy + -3y) = 4y + -12(xy + -3y) = 4y + -12
then we would Reorder the terms:xy + -3y = -12 + 4y
then you would Move all terms containing x to the left, all other terms to the right.
so that means we would Add '3y' to each side of the equation.xy + -3y + 3y = -12 + 4y + 3y
then you would want to Combine like terms: -3y + 3y = 0xy + 0 = -12 + 4y + 3y xy = -12 + 4y + 3y
Combine these two 4y + 3y = 7yxy = -12 + 7y
then we would want to Divide each side by 'y'.x = -12y-1 + 7
so after simplifying it, it would be x = 7 + -12y-1
y(x + -3) = 4y + -12\
Then you would Reorder the terms:
y(-3 + x) = 4y + -12 (-3 * y + x * y) = 4y + -12
And theses (xy + -3y) = 4y + -12(xy + -3y) = 4y + -12
then we would Reorder the terms:xy + -3y = -12 + 4y
then you would Move all terms containing x to the left, all other terms to the right.

Combine these two 4y + 3y = 7yxy = -12 + 7y
then we would want to Divide each side by 'y'.x = -12y-1 + 7
so after simplifying it, it would be x = 7 + -12y-1
remember yuo can do anything to an equaiton as long as you do it to both sides
(x-3)=4y-12
x-3=4y-12
add 12 both sides
x-3+12=4y+12-12
x+9=4y+0
x+9=4y
divid both sides by 4
(x+9)/4=y
(x-3)=4y-12
x-3=4y-12
add 12 both sides
x-3+12=4y+12-12
x+9=4y+0
x+9=4y
divid both sides by 4
(x+9)/4=y
