(5ab-4a-8)-(9ab-5)
Ok just remember that the minus sign before the (9ab-5) is like a minus 1 so it changes the sign inside the bracket...
>>5ab-4a-8-9ab+5
>>-4ab-4a-3
I'm guessing you just have to leave it like that unless there are other parts to the question or whatever but that's that simplified as far as it can be!
-8 you divide and since there is a negative you add a negative
5m + 4m = 72
Combine like terms.
9m = 72
Divide both sides by 9.
m = 8
