Answer 1

Given:

`52\text{ = 4(c + 5)}`

Solution

We are required to solve the equation for c.

First, we open the bracket:

`52\text{ = 4c + 20}`

Next, we make c the subject of formular:

`\begin{gathered} 4c\text{ = 52 - 20} \\ 4c\text{ = 32} \\ \text{Divide both sides of the equation by 4} \\ c\text{ = 8} \end{gathered}`

Answer: c = 8
