6x-12y+6-10x=-5y+5
Subtract 10x from both sides.
-4x-12y+6=-5y+5
Combine 6x and -10x to get -4x.
-4x+6=-5y+5+12y
Add 12y to both sides.
-4x+6=7y+5
Combine -5y and 12y to get 7y.
-4x=7y+5-6
Subtract 6 from both sides.
-4x=7y-1
Subtract 6 from 5 to get -1.
\frac{-4x}{-4}=\frac{7y-1}{-4}
Divide both sides by -4.
x=\frac{7y-1}{-4}
Dividing by -4 undoes the multiplication by -4.
x=\frac{1-7y}{4}
Divide 7y-1 by -4.
6x-12y+6+5y=10x+5
Add 5y to both sides.
6x-7y+6=10x+5
Combine -12y and 5y to get -7y.
-7y+6=10x+5-6x
Subtract 6x from both sides.
-7y+6=4x+5
Combine 10x and -6x to get 4x.
-7y=4x+5-6
Subtract 6 from both sides.
-7y=4x-1
Subtract 6 from 5 to get -1.
\frac{-7y}{-7}=\frac{4x-1}{-7}
Divide both sides by -7.
y=\frac{4x-1}{-7}
Dividing by -7 undoes the multiplication by -7.
y=\frac{1-4x}{7}
Divide 4x-1 by -7.
