mohon bantuannya dengan caranya

misal 1/(2p + q ) = a dan 1/(2p - q) = b, maka
4a + 5b = 1
2a - 5b = 2
--------------- +
6a = 3
a = 3/6 = 1/2, dari 4a + 5b = 1
4.1/2 + 5b = 1
2 + 5b = 1
5b = 1-2
5b = -1. maka b = -1/5
2p + q = 1/2. ==» 2p + q = 2
2p - q = -1/5.==» 2p - q = -5
--------------- -
2q = 7, q = 7/2
2p + q = 2
2p - q = -5
--------------- +
4p = -3, p = -3/4
4p + q = 4.(-3/4) + 7/2
= -3 + 7/2
= -6/2 + 7/2
= 1/2
kamu mengintip ya.......?
