5.18-21.7c+15.4c=-13.09
Add 15.4c to both sides.
5.18-6.3c=-13.09
Combine -21.7c and 15.4c to get -6.3c.
-6.3c=-13.09-5.18
Subtract 5.18 from both sides.
-6.3c=-18.27
Subtract 5.18 from -13.09 to get -18.27.
c=\frac{-18.27}{-6.3}
Divide both sides by -6.3.
c=\frac{-1827}{-630}
Expand \frac{-18.27}{-6.3} by multiplying both numerator and the denominator by 100.
c=\frac{29}{10}
Reduce the fraction \frac{-1827}{-630} to lowest terms by extracting and canceling out -63.
