Consider the equation 3p - 7 + p = 13. What is the resulting equation after the first step in the solution?
Op-7 = 13 – 3p
2p - 7 = 13
3p - 7 = 13-p
4p - 7 = 13

answer:

p=5

Step-by-step explanation:

4p-7=13

After the first step which is combining like terms, so add the 3p and the single p together.

Next, the negative 7 turns to a positive when we exterminate it from one half of the equation and add it towards the second part.

4p-7=13

+7. +7

4p=20

Divide both sides by 4 to get the p alone.

4p=20

/4. /4

P=5

That is the answer to the entire equation, again though the first step answer is at the very top, i just felt like solving it for you as well.

your answer is  

a.

5
