Question

Solve for p. 9(p-4) = -18 p=

Answer 1

First you want to use the distributive property.  So, $9*p-(9*4)=-18$.  Which equals $9p-36=-18$.  Next use the addition property of equality to make your first step to isolate variable p.  Which equals $9p-36+36=-18+36$.  Then simplify the equation down to $9p=18$.  Lastly, is the division property of equality $(9p)/9=18/9$.  Once again simplify to $p=2$.  Always make sure to pull your answer back into the original equation to see if the answer is correct.

$9(2-4)=-18$

$9(-2)=-18$

$-18=-18$

Answer 2

Step-by-step explanation:

9(p-4) = -18

9p - 36 = -18

9p = -18 + 36

9p = 18

p= 18/9

p = 2

Check:

9 ( 2 - 4 ) = - 18

9 (-2) = - 18

- 18 = - 18
