5(n+1) = 2n + 20 can someone tell me the answer and explain

First we have to expand 5(n + 1)
Meaning we have to multiply everything in the bracket by 5. That would mean 5n + 5.

Now we have 5n + 5 = 2n +20

Subtract 2n from both sides to get rid of the 2n on the right

So you will have 3n + 5 = 20

Now subtract 5 from both sides to get rid of the 5 on the left.

So you will have 3n = 15

Divide both sides by 3 to get n = 5

Answer is n = 5
