Consider the equation 3p – 7 + p = 13. what is the resulting equation after the first step in the solution?

The first step you would do to solve this equation is to put numbers on one side and variables on the other. Right now, you have 3p - 7 + p = 13, which is close, but -7 is in the side of the variables. So, in order to get -7 to the other side, you simply just move -7 to the other side. (Remember that once you move the number or variable to the other side, you have to change the negative to a positive or a positive to a negative) So your result would be 3p + p = 13 + 7.

C. 3p – 7 = 13 – p

Step-by-step explanation:

3p-7+p=13

We simplify the equation to the form, which is simple to understand  

3p-7+p=13

We move all terms containing p to the left and all other terms to the right.  

+3p+1p=+13+7

We simplify left and right side of the equation.  

+4p=+20

We divide both sides of the equation by 4 to get p.  

p=5

12+3b -1=-5-b -12-1+5=-b-3b -8=-4b
