Expand the parenthesis:

4(7 + 8p) --> 28 + 32p

28 + 32p = 2p - 2

Subtract 28 from both sides:

32p = 2p - 30

Subtract 2p from both sides:

30p = -30

Divide both sides by 30

p = -1

Answer:

p = -1

Step-by-step explanation:

4(7 + 8p) = 2p – 2

28 + 32p = 2p - 2

+ 32p - 2p = - 2 - 28

30p = - 30

p = -30/30

p = -1
