Whats the anwser to -3(p - 5) - 7p + 2(p - 18)?

Question

i'm stuck on this math problem i need some help

Answer 1

-3(p - 5) - 7p + 2(p - 18)
-3p+15-7p+2p-36
-8p-21
-8p=21
p=-21/8

Answer 2

Just multiply it out and add like terms. Remember, the biggest mistake most young math students make is the distributive property. The sign in front of a number always goes with it, and minus times a minus equals a plus. So, here's the first step: Multiply it out.

-3p +15 -7p +2p -36

Now, put like terms together and add like terms:
-3p-7p+2p + 15-36
-8p -21

Answer 3

-3(p - 5) - 7p + 2(p - 18)?

distrube, follow this formula:
a(b + c) = ab + ac
or a(b - c) = ab - ac

distribute the -3 and the 2
-3p -3(-5) - 7p + 2p - 2(18)

-3p + 15 - 7p + 2p - 36

combine like terms, but first rearrange the terms
-3p - 7p + 2p + 15 - 36

combine like terms
-8p - 21

Answer 4

-3(p - 5) - 7p + 2(p - 18)
-3p+15-7p+2p-36 add the p's
-8p+15-36
-8p-21

Answer 5

-3p+15-7p+2p-36
= -8p-21 simply that all you need

if you need to find the value of p
if you let -8p-21=0
then p= -21/8

Answer 6

= - 3p + 15 - 7p + 2p - 36
= - 8p - 21
= - (8p + 21)

Answer 7

wl, simplified, it would be -3p + 15 - 7p + 2p -36 = -8p-21. Sorry if it's wrong!!

Answer 8

-3(p-5)-7p+2(p-18)
=-3p+15-7p+2p-36
=-8p-21

Answer 9

3p - 21
