3 (c+5) = 12

so what does c=?

Answer: C=-1

Solve equation step by step

3 (c+5) = 12

Step 1: simplify both side of the equation.

3 (c+5) = 12 and distribute them

Step 2: Subtract 15 from both sides.

3c+15-15=12-15

3c=-3

Step 3: Divide both sides by 3.

3c/3=-3/3

C=-1

Answer: 4

Step-by-step explanation:

12 - 5 = 7,

7 - 3 = 4.

The answer to this is 4.
