Answer:
I think what they are looking for in section A) is 4x+10
and in section B) 18
Step-by-step explanation:
In order to get the answer for A you must add like terms. Each side has a x meaning x multiplied by 4 or 4x then you have 5 on each length meaning 10 so when you put those together you get 4x+10.
In order for you to find Bs solution you subtract 10 from 62 which is 52 then divide 52 by four for each x and 52 divided by 4=13 so x=13 and then you add 5 to 13 to get 18 which is the length
