Answer-

Given equations are

x/5 - y/3 = 4/15 ...(i)

x/2 - y/9 = 7/18 ...(ii)

Now, multiplying (i) by (1/2) and (ii) by (1/5), we get

x/10 - y/6 = 2/15

x/10 - y/45 = 7/90

On subtraction, we get

13y/90 = - 1/18

or, y = - 5/13

Now, putting y = - 5/13 in (i), we get

x/5 - (- 5/13)/3 = 4/15

or, x/5 = 4/15 - 5/39

or, x/5 = 9/65

or, x = 9/13

Therefore, the required solution be

x = 9/13 and y = - 5/13
