Given:

Twelve times the sum of a number and three is 72

A) we will write an equation to translate the given statement

Let the number = x

So, the equation will be:


12(x+3)=72

B) we will solve the equation to find x

First, divide both sides by 12


\begin{gathered} (12(x+3))/(12)=(72)/(12) \\ \\ x+3=6 \end{gathered}

Then, subtract 3 from both sides


\begin{gathered} x+3-3=6-3 \\ x=3 \end{gathered}

So, the answer will be x = 3
