Answer :

The value of p is 1.

Given,

2/5 + p = 4/5 + (3/5)p

We need to find what is p.

We have,

2/5 + p = 4/5 + (3/5)p

Keep like terms on one side.

Subtract p on both sides.

2/5 + p - p = 4/5 + (3/5)p - p

2/5 = 4/5 + (3/5)p - p

Subtract 4/5 on both sides.

2/5 - 4/5 = 4/5 + (3/5)p - p - 4/5

2/5 - 4/5 = (3/5)p - p

(2 - 4) / 5 = (3p - 5p) / 5

-2 / 5 = -2p / 5

Minus canceled on both sides.

2 / 5 = (2 / 5)p

2/5 gets canceled on both sides

1 = p

p = 1

Thus the value of p is 1.
