If 7(p+3)= -28 then what does p equal

p = -7

Step-by-step explanation:

7(p+3) = -28

now we times the inside of the parenthese by 7

7p+21 =-28

now we minus 21 on both sides

7p= -49

now divide

p = - 7

-7

Step-by-step explanation:

7(p+3) = -28

Divide by 7

7(p+3) / 7 = -28 / 7

p+3 = -4

Subtract 3

p+3 (-3) = -4 (-3)

P = -7
