3478-3c=5y
Swap sides so that all variable terms are on the left hand side.
-3c=5y-3478
Subtract 3478 from both sides.
\frac{-3c}{-3}=\frac{5y-3478}{-3}
Divide both sides by -3.
c=\frac{5y-3478}{-3}
Dividing by -3 undoes the multiplication by -3.
c=\frac{3478-5y}{3}
Divide 5y-3478 by -3.
5y=3478-3c
The equation is in standard form.
\frac{5y}{5}=\frac{3478-3c}{5}
Divide both sides by 5.
y=\frac{3478-3c}{5}
Dividing by 5 undoes the multiplication by 5.
