4x=16+7y
Add 7y to both sides.
4x=7y+16
The equation is in standard form.
\frac{4x}{4}=\frac{7y+16}{4}
Divide both sides by 4.
x=\frac{7y+16}{4}
Dividing by 4 undoes the multiplication by 4.
x=\frac{7y}{4}+4
Divide 16+7y by 4.
-7y=16-4x
Subtract 4x from both sides.
\frac{-7y}{-7}=\frac{16-4x}{-7}
Divide both sides by -7.
y=\frac{16-4x}{-7}
Dividing by -7 undoes the multiplication by -7.
y=\frac{4x-16}{7}
Divide 16-4x by -7.
