16x+18=4y
Swap sides so that all variable terms are on the left hand side.
16x=4y-18
Subtract 18 from both sides.
\frac{16x}{16}=\frac{4y-18}{16}
Divide both sides by 16.
x=\frac{4y-18}{16}
Dividing by 16 undoes the multiplication by 16.
x=\frac{y}{4}-\frac{9}{8}
Divide 4y-18 by 16.
4y=16x+18
The equation is in standard form.
\frac{4y}{4}=\frac{16x+18}{4}
Divide both sides by 4.
y=\frac{16x+18}{4}
Dividing by 4 undoes the multiplication by 4.
y=4x+\frac{9}{2}
Divide 16x+18 by 4.
