7x=3+20y
Add 20y to both sides.
7x=20y+3
The equation is in standard form.
\frac{7x}{7}=\frac{20y+3}{7}
Divide both sides by 7.
x=\frac{20y+3}{7}
Dividing by 7 undoes the multiplication by 7.
-20y=3-7x
Subtract 7x from both sides.
\frac{-20y}{-20}=\frac{3-7x}{-20}
Divide both sides by -20.
y=\frac{3-7x}{-20}
Dividing by -20 undoes the multiplication by -20.
y=\frac{7x-3}{20}
Divide 3-7x by -20.
