2x=y+19-7
Subtract 7 from both sides.
2x=y+12
Subtract 7 from 19 to get 12.
\frac{2x}{2}=\frac{y+12}{2}
Divide both sides by 2.
x=\frac{y+12}{2}
Dividing by 2 undoes the multiplication by 2.
x=\frac{y}{2}+6
Divide y+12 by 2.
y+19=2x+7
Swap sides so that all variable terms are on the left hand side.
y=2x+7-19
Subtract 19 from both sides.
y=2x-12
Subtract 19 from 7 to get -12.
