I'm assuming this is
3/x+3/y=11/10
5/x+18/y = 4
Multiply the first equation by -5 and the second by 3 .... this gives
-15/x - 15/x = -5.5
15/x + 54/y = 12 add these
39/y = 6.5
39/y = 13/2 and we can write
y / 39 = 2/13 multiply by 39
y = 39 * 2 / 13 = 78/13 = 6
And putting this into the second equation for, y....we have
5/x + 18/6 = 4
5/x + 3 = 4 subtract 3 from both sides
5/x = 1 which implies that x = 5
