Answer:
c = -2
Explanation:
The first step in solving for c is to add 27 to both sides of the equation. This gives
[tex]-12c-27+27=-3+27[/tex]27 cancels on the left-hand side to give
[tex]-12c=-3+27[/tex][tex]-12c=24[/tex]dividing both sides by -12 gives
[tex]-\frac{12c}{-12}=\frac{24}{-12}[/tex]the -12 cancels on the left-hand side to give
[tex]c=-\frac{24}{12}[/tex][tex]\boxed{c=-2.}[/tex]which is our answer!
