Question

When the expression 3(n+7) is evaluated for a given value of n the result is 33 what is the value of n

Answer 1

To find the corresponding n value for the expression when the expression is equal to 33, we just need to solve the following equation

$3(n+7)=33$

First, let's divide both sides by 3

$\begin{gathered} \frac{3(n+7)}{3}=\frac{33}{3} \\ n+7=11 \end{gathered}$

Then, let's subtract 7 from both sides

$\begin{gathered} n+7-7=11-7 \\ n=4 \end{gathered}$

The corresponding value for n is 4.
