igreen · Answer

Plug in 12:

(–7 + 12) + (–14) = (12 + (–7)) + (–14)

Add:

5 - 14 = 12 - 7 - 14

Subtract:

-9 = 12 - 7 - 14

Subtract:

-9 = 5 - 14

Can you subtract 5 - 14? @christine_

9

igreen · Answer

No, it's -9.

So that gives you -9 = -9, which is true..so 12 is the answer.
