Answer:Simplifying
2p + - 7 = 13 + - 8p
Reorder the terms:
-7 + 2p = 13 + - 8p
Solving
-7 + 2p = 13 + - 8p
Solving for variable 'p'.
Move all terms containing p to the left, all other terms to the right.
Add '8p' to each side of the equation.
-7 + 2p + 8p = 13 + - 8p + 8p
Combine like terms: 2p + 8p = 10p
-7 + 10p = 13 + - 8p + 8p
Combine like terms: - 8p + 8p = 0
-7 + 10p = 13 + 0
-7 + 10p = 13
Add '7' to each side of the equation.
-7 + 7 + 10p = 13 + 7
Combine like terms: - 7 + 7 = 0
0 + 10p = 13 + 7
10p = 13 + 7
Combine like terms: 13 + 7 = 20
10p = 20
Divide each side by '10'.
p = 2
Simplifying
p = 2
