3-20=2c
Multiply both sides of the equation by 4.
-17=2c
Subtract 20 from 3 to get -17.
2c=-17
Swap sides so that all variable terms are on the left hand side.
c=\frac{-17}{2}
Divide both sides by 2.
c=-\frac{17}{2}
Fraction \frac{-17}{2} can be rewritten as -\frac{17}{2} by extracting the negative sign.
