x-12-2\left(x-y\right)-y=0
Multiply both sides of the equation by 6, the least common multiple of 6,3.
x-12-2x+2y-y=0
Use the distributive property to multiply -2 by x-y.
-x-12+2y-y=0
Combine x and -2x to get -x.
-x+2y-y=12
Add 12 to both sides. Anything plus zero gives itself.
-x-y=12-2y
Subtract 2y from both sides.
-x=12-2y+y
Add y to both sides.
-x=12-y
Combine -2y and y to get -y.
\frac{-x}{-1}=\frac{12-y}{-1}
Divide both sides by -1.
x=\frac{12-y}{-1}
Dividing by -1 undoes the multiplication by -1.
x=y-12
Divide 12-y by -1.
x-12-2\left(x-y\right)-y=0
Multiply both sides of the equation by 6, the least common multiple of 6,3.
x-12-2x+2y-y=0
Use the distributive property to multiply -2 by x-y.
-x-12+2y-y=0
Combine x and -2x to get -x.
-12+2y-y=x
Add x to both sides. Anything plus zero gives itself.
2y-y=x+12
Add 12 to both sides.
y=x+12
Combine 2y and -y to get y.
