Question from Terence:

5/x-6/y=1
17/x+30/y=16
I been spending whole day to solve this question. Would be very grateful if you can help I try
The denominator value is a equations term which make is simultaneous equations so hard.

Hi Terence,

First of all write as 5 \times \large \frac{1}{x} and similarly for the other fractions. Next substitute s = \large \frac1{x} and t = \large \frac1{y}. Solve for s and t.
