Hey there!
First we have to [tex]distribute [/tex]!
[tex]-4 (p +2) = +8 = 2(p - 1) -7p + 15 \\ -4(p) + -4(2) + 8 = 2(p) +-2 + -7p + 15 [/tex]
Now, we have to [tex]combine [/tex] our like terms
[tex]-4p + (-8 + 8) = 2p + (-7p) + (-2) + 15
[/tex]
Once we solve all the [tex]like-terms [/tex] we get
[tex]-4p = 5p +13 [/tex]
Now, we have to [tex]add[/tex] [tex]5p [/tex] to each of your sides
[tex]-4p + 5p \\ = -5p + 13 + 5p [/tex]
Solve that part of the equation
[tex]p= 13 [/tex]
Good luck on your assignment and enjoy your assignment
