I'm assuming this is a eraction:

7(-7) - 7(2 -3) / 2(-6 + 9) =
(-49 - 7*-1) / 2*3 = (-49 + 7) /6 =
-42 /6 = -7.

/ 6

Hi Henry,

Can you tell me if the answer was -7/6 because that isn't one of my multiple choices. The multiple choices are -7; 10; -28/3; or -7/5. Thanks for clarification. I really appreciate your help.
