12y+12x=20y+2z
Multiply both sides of the equation by 4.
12x=20y+2z-12y
Subtract 12y from both sides.
12x=8y+2z
Combine 20y and -12y to get 8y.
\frac{12x}{12}=\frac{8y+2z}{12}
Divide both sides by 12.
x=\frac{8y+2z}{12}
Dividing by 12 undoes the multiplication by 12.
x=\frac{z}{6}+\frac{2y}{3}
Divide 8y+2z by 12.
12y+12x=20y+2z
Multiply both sides of the equation by 4.
12y+12x-20y=2z
Subtract 20y from both sides.
-8y+12x=2z
Combine 12y and -20y to get -8y.
-8y=2z-12x
Subtract 12x from both sides.
\frac{-8y}{-8}=\frac{2z-12x}{-8}
Divide both sides by -8.
y=\frac{2z-12x}{-8}
Dividing by -8 undoes the multiplication by -8.
y=\frac{3x}{2}-\frac{z}{4}
Divide 2z-12x by -8.
