how do I work this problem 3(n+5)+2=26

Question

I am trying to help my grandson with his work. The problem is 3(n+5)+2=26

Answer 1

3(n + 5) + 2 = 26
3n + 15 + 2 = 26 {used distributive property}
3n + 17 = 26 {combined like terms}
3n = 9 {subtracted 17 from both sides}
n = 3 {divided both sides by 3}
