Question
The area of a rectangle pool was 120 square meters. If the long side is 7 meters plus a number and the width is 6 meters. What is the value of the variable?
I couldn't make a equation for this; I tried and I got 7+x+6 = 120 and that doesn't seem right.

You are correct to feel ill at ease. You have confused area and perimeter. You want
(x+7)(6) = 120
(x+7)(6) = 120
