Question

What is the value of n? 34 = 7n - 15

Answer 1

n = 7 (option B)

Step-by-step explanation

First we have to add 15 on both sides of the equation:

`\begin{gathered} 34+15=7n-15+15 \\ 49=7n \end{gathered}`

Now, we have to divide both sides by 7:

`\begin{gathered} (49)/(7)=(7n)/(7) \\ 7=n \end{gathered}`
