-p+10=2(p+8)

Question

step by step to answer -p+10=2(p+8)

Answer 1

-p + 10 = 2p + 16
10 - 16 = 2p + p
-6 = 3p
-2 = p

Answer 2

We want to get p by itself on one side of the equal sign. We can add, subtract, multiply, and divide as long as we do it to both sides.

 

First, distribute the 2:

-p + 10 =2(p +8)

-p + 10 =2p + 16

Now add p to both sides to get rid of the p on the left.

-p + 10 +p = 2p + 16 +p

10 = 3p + 16

Subtract 16 from both sides.

10 - 16 = 3p + 16 - 16

-6 = 3p

Divide both sides by 3.

-6/3 = 3p/3

-2 = p

 

Hope that helps.
