4x=5+7y
Add 7y to both sides.
4x=7y+5
The equation is in standard form.
\frac{4x}{4}=\frac{7y+5}{4}
Divide both sides by 4.
x=\frac{7y+5}{4}
Dividing by 4 undoes the multiplication by 4.
-7y=5-4x
Subtract 4x from both sides.
\frac{-7y}{-7}=\frac{5-4x}{-7}
Divide both sides by -7.
y=\frac{5-4x}{-7}
Dividing by -7 undoes the multiplication by -7.
y=\frac{4x-5}{7}
Divide 5-4x by -7.
