Twelve times the sum of a number and three is 72. What is the number?

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:
[tex]12(x+3)=72[/tex]B) we will solve the equation to find x
First, divide both sides by 12
[tex]\begin{gathered} \frac{12(x+3)}{12}=\frac{72}{12} \\ \\ x+3=6 \end{gathered}[/tex]Then, subtract 3 from both sides
[tex]\begin{gathered} x+3-3=6-3 \\ x=3 \end{gathered}[/tex]So, the answer will be x = 3
