yoo.
Answer:
=> p = 3.5
Step-by-step explanation:
p - ( 2p + 5 ) - 5(1 - 2p) = 2(3 + 4p) - 3(p - 4)
=> (removing brackets and multiplying)
=> p - 2p -5 - 5 + 10p = 6 + 4p - 3p + 12
=>( Why ? I make some sign change
Answer : Because There Are Some Where - ( a - c ) like thing in This scenario We Shall Make It as -a + c . Because We Can Take That { - } Sign As { -1 } Because of Signs Will Be changed according to sign change rule )
=>(Gathering all p at one place and all constants at one place)
=> p - 2p + 10p - 4p +3p = 5 + 5 + 6 + 12 (Signs Will Be changed After Side Changing)
=> 8p = 28
=> p = 28 / 8
=> p = 14 / 4
=> p = 7 / 2
=> p = 3.5
