In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data
1/3(x+18)= 7
x = ?
Step 02:
We must apply the algebraic rules to find the solution.
[tex]\begin{gathered} \frac{1}{3}\cdot(x+18)=7 \\ x\text{ + 18 = 3}\cdot7 \\ x=21-18\text{ = 3} \end{gathered}[/tex]The answer is:
x = 3
