7x=3+4y
Add 4y to both sides.
7x=4y+3
The equation is in standard form.
\frac{7x}{7}=\frac{4y+3}{7}
Divide both sides by 7.
x=\frac{4y+3}{7}
Dividing by 7 undoes the multiplication by 7.
-4y=3-7x
Subtract 7x from both sides.
\frac{-4y}{-4}=\frac{3-7x}{-4}
Divide both sides by -4.
y=\frac{3-7x}{-4}
Dividing by -4 undoes the multiplication by -4.
y=\frac{7x-3}{4}
Divide 3-7x by -4.
