-1-c\leq -6.18
Swap sides so that all variable terms are on the left hand side. This changes the sign direction.
-c\leq -6.18+1
Add 1 to both sides.
-c\leq -5.18
Add -6.18 and 1 to get -5.18.
c\geq \frac{-5.18}{-1}
Divide both sides by -1. Since -1 is negative, the inequality direction is changed.
c\geq \frac{-518}{-100}
Expand \frac{-5.18}{-1} by multiplying both numerator and the denominator by 100.
c\geq \frac{259}{50}
Reduce the fraction \frac{-518}{-100} to lowest terms by extracting and canceling out -2.
