Question

need help with 3 easy math problems​

Answer 1

Answer:

p=9 m=21 x= - 30

Step-by-step explanation:

p=9

m=21

x= - 30

Answer 2

Step-by-step explanation:

1) 3p + 5 = 14

3p = 14 - 5

3p = 9

p = 9/3

⇢ p = 3

2)

m/7 - 3 = 0

m/7 = 3

m = 3 × 7

⇢ m = 21

3) 8 + x/2 = -7

x/2 = -7 - 8

x/2 = - 15

⇢ x = -30
