Question

Solve an equation

2p+20% of (2p-1)=7

Answer 1

2p + 20( 2p - 1 ) / 100 = 7

2p + ( 2p - 1 ) /5 = 7

10p + 2p-1 = 35

12p = 35 + 1 = 36

p = 36 /12 = 3

$<h4>Value of p = 3.</h4>$

Answer 2

Solution :

Given 2p + 20%of ( 2p - 1 ) = 7

=> 2p + ( 20/100 ) ( 2p - 1 ) = 7

=> 2p + (1/5 )(2p - 1 ) = 7

=> [ 10p + 2p - 1 ]/5 = 7

=> 12p - 1 = 35

=> 12p = 36

=> p = 36/12

=> p = 3
