Not really because the first obe would be 8x-20 and the second one would be x+15. Hint: The "more than" and "less than" tells that number to be last.

to answer this, we'll first build an equation and solve it,
x=the number

8x-20=x+15
-x -x
=7x-20=15
+20 +20
=7x=35
÷7 ÷7
=x=5

your answer is 5

check,
8×5-20=20
5+15=20

answer=5
