3x=6y+10+2
Add 2 to both sides.
3x=6y+12
Add 10 and 2 to get 12.
\frac{3x}{3}=\frac{6y+12}{3}
Divide both sides by 3.
x=\frac{6y+12}{3}
Dividing by 3 undoes the multiplication by 3.
x=2y+4
Divide 12+6y by 3.
6y+10=3x-2
Swap sides so that all variable terms are on the left hand side.
6y=3x-2-10
Subtract 10 from both sides.
6y=3x-12
Subtract 10 from -2 to get -12.
\frac{6y}{6}=\frac{3x-12}{6}
Divide both sides by 6.
y=\frac{3x-12}{6}
Dividing by 6 undoes the multiplication by 6.
y=\frac{x}{2}-2
Divide -12+3x by 6.
