@mthompson440 I still don't get it.

Answer 3

What do you get when you divide -12 by -3?

Answer 4

@mthompson440 4.

Answer 5

yes, so your new equation now looks like x+7=4
So what plus seven equals four?

Answer 6

@mthompson440 -3

yes, -3 is one of your answers. Good job.
Now, what else? What number could you take seven away from and still have four?

Answer 8

I'm sorry
I meant what number could you take seven away from and have -3?

Answer 9

@mthompson440 11?

Answer 10

Yes, but think positive seven = -3
-11+7 = -3

Answer 11

wow, my typing is bad

Answer 12

Would it be x= -3 and x= 11?

-11+7=4
so you answers are -3, and -11
