Question

true of false math question!!

Answer 1

1st things 1st remember a NEGATIVE next to a NEGATIVE gives you a + so it would be 9a+72=0 Can you solve that?

Answer 2

release the brackets
-(-72)=+72=72
so 9a+72=0

subtract 72 from both sides
9a+72-72=0-72
9a=-72
divide both sides by 9
9/9*a=-72/9
a=-8
