Ijust need the answer to this picture

As negative and negative is positive (adding) and stays negative

12+3= 15

-15+7

As 7 is positive, negative and positive is negative (you substract but the answer stays negative because the bigger number is negative)

15-7=8

-8

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this
