Math Problem Statement

Solve for c in the equation 18 = 4c + 2.

Solution

Let's solve the equation step-by-step from the image.

The equation given is:

18=4c+218 = 4c + 2

Step 1: Subtract 2 from both sides

182=4c18 - 2 = 4c 16=4c16 = 4c

Step 2: Divide both sides by 4

164=c\frac{16}{4} = c c=4c = 4

So, the solution is c=4c = 4.
