Question

solve 2/x + 3/y =13, 5/x + 7/y =31​

Answer 1

Answer:x=1/32 & y=1/-17

Step-by-step explanation:

Let 1/x = p and 1/y =q, then our equations become:

2p+3q = 13 ………. (1)

5p+7q = 31………… (2)

Solving these equations by any method; we get:

q = -17

Put in eq. 1 we get:

p = 32

But, p=1/x. So x=1/32

And q=1/y so y=1/-17

Hope it may help....
