Well first u gotta simplify the equation by multiplying the outside number (the 5) into the parenthesis.

Original: 5(-3p+7)
simplified: -15p+35

and then you do the same for the other part.

Original: 5(p-1)
Simplified: 5p-5

Now thats done, you now have the new equation as -15+35+5p-5

And finally you combine like terms and your final answer should be -10p+30
