4x=2y-57
Subtract 57 from both sides.
\frac{4x}{4}=\frac{2y-57}{4}
Divide both sides by 4.
x=\frac{2y-57}{4}
Dividing by 4 undoes the multiplication by 4.
x=\frac{y}{2}-\frac{57}{4}
Divide 2y-57 by 4.
2y=4x+57
Swap sides so that all variable terms are on the left hand side.
\frac{2y}{2}=\frac{4x+57}{2}
Divide both sides by 2.
y=\frac{4x+57}{2}
Dividing by 2 undoes the multiplication by 2.
y=2x+\frac{57}{2}
Divide 4x+57 by 2.
