Step-by-step explanation:

1. 10+m= -9                                  ANSWER: M= -19

subtract 10 from both sides (m=−9−10)

Subtract 10 from −9 to get −19.

2. -12x= 60                                    ANSWER: X= -5

Divided both sides by negative 12 (x= 60 over -12)

Divide 60 by −12 to get −5.

3. v/20 = 7                                      ANSWER: V= 140

Multiply both sides by 20 (v=7×20)

Multiply 7 and 20 to get 140.
