-1b-3a I believe. You start by subtracting 8b from 7b, from which you would get -1b. Then, since there are no other integers paired with the variable a, you just leave the expression as -1b-3a. If you knew what the variables stood for, then you could simplify this expression further, but with the information provided, this is the simplest answer.

Hey there!

7b - (3a - 8b)

= 7b -1(3a - 8b)

= 7b -1(3a) - 1(-8b)

= 7b - 3a - 8b

= 15b - 3a

= -3a + 15b

Therefore, your answer is: -3a + 15b

Good luck on your assignment and enjoy your day!
