Explanation:
Sure! Let's solve the equation step by step:
Given equation: 55 = 9c + 13 - 2c
First, let's combine like terms on the right side of the equation:
55 = (9c - 2c) + 13
Simplifying further:
55 = 7c + 13
Next, let's isolate the variable term by subtracting 13 from both sides of the equation:
55 - 13 = 7c
Simplifying:
42 = 7c
To solve for c, we can divide both sides of the equation by 7:
42/7 = c
Simplifying:
6 = c
Therefore, the solution to the equation is c = 6.
