Chance Roman · Answer 1

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

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.
