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.
