misalkan a = 1/x dan b= 1/y
1/x + 1/y  = 1/2 → a + b = 1/2 ...(i)
2/x - 3/y = 1/6  → 2a -3b = 1/6 ...(ii)

(i) dan (ii) eliminasi
a  +  b = 1/2 ...}kali 2
2a - 3b = 1/6

2a + 2b = 1
2a - 3b = 1/6 | (-)
5b = 5/6
b = 1/6→ y = 1/b = 6

a  + b  =1/2
a + 1/6 = 1/2
a = 1/2 -1/6
a = 1/3  → x  = 1/a=  3

x,y = (3, 6)
