7p−(3p+4)=−2(2p−1)+10
7p+−1(3p+4)=−2(2p−1)+10(Distribute the Negative Sign)
7p+−1(3p)+(−1)(4)=−2(2p−1)+10
7p+−3p+−4=−2(2p−1)+10
7p+−3p+−4=(−2)(2p)+(−2)(−1)+10(Distribute)
7p+−3p+−4=−4p+2+10
(7p+−3p)+(−4)=(−4p)+(2+10)(Combine Like Terms)
4p+−4=−4p+12
4p−4=−4p+12
Add 4p to both sides.
4p−4+4p=−4p+12+4p
8p−4=12
Add 4 to both sides.
8p−4+4=12+4
8p=16
Divide both sides by 8
p=2 <----final answer :)
