3\left(-1\right)\geq c+1
Multiply both sides by -1. Since -1 is negative, the inequality direction is changed.
-3\geq c+1
Multiply 3 and -1 to get -3.
c+1\leq -3
Swap sides so that all variable terms are on the left hand side. This changes the sign direction.
c\leq -3-1
Subtract 1 from both sides.
c\leq -4
Subtract 1 from -3 to get -4.
