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.

7(-7)-7(2-3)

____________

2(-6+9)

top: 7(-7)-7(-1)= -49+7=-42

bottom: 2(3)=6

-42/6=?

Yes, the answer is -42/6 = -7.
