The problem is


-40+7p=3+5(8p-2);p=-1

To solve this problem, we need to replace the numerical value of p, and see if it satisfies. After replacing the value, we will solve the parenthesis first


-40+7(-1)=3+5(8(-1)-2)
-40-7=3+5(-8-2)
-47=3+5(-10)\rightarrow-47=3-15\rightarrow-47=-12

As you can observe, the value -1 for p doesn't satisfy the equation, that means, it's not a solution.

Therefore, the right answer is NO.
