Question
Hi,
I need to find the "truth set" i.e. the set of points that satisfy BOTH these conditions at all times:
- xy = 9
- 3x - 4y =1
With a lot of algebraic manipulation - and a final check on Wolfam Alpha I see I got it right (image embedded) but it took screeds of scribbling and substitution.
Can you please advse if you think a concise set of steps would acheive the same goal? Say 4-5 lines, including working, and reply with these
Many Thanks
Kim
