12.79=3c+1
The opposite of -1 is 1.
3c+1=12.79
Swap sides so that all variable terms are on the left hand side.
3c=12.79-1
Subtract 1 from both sides.
3c=11.79
Subtract 1 from 12.79 to get 11.79.
c=\frac{11.79}{3}
Divide both sides by 3.
c=\frac{1179}{300}
Expand \frac{11.79}{3} by multiplying both numerator and the denominator by 100.
c=\frac{393}{100}
Reduce the fraction \frac{1179}{300} to lowest terms by extracting and canceling out 3.
