Define a variable. Then write an equation that could be used to solve each problem?

The second page from my first. Thank you guys for all your help!

5.) GRADES; Kelly's test score was 6 points higher than Michelle's. If Kelly's test score was 88, what was Michelle's test score?

6.) GEOMETRY; A rectangles width is one-third its length. If the width is 8 inches, what is the length of the rectangle?

7.)FOOTBALL A team had a total gain of -15 yards over several plays with an average gain of -5 yards per play. How many plays are represented?

(The same thing as the other question but a different question if you understand)
