Question

Solve the equation by reducing them to a pair of the linear equation:

2p−3q=4pq,

5p+7q=72pq​

Answer 1

Step-by-step explanation:

$2p - 3q = 4pq......(1)$

$5p + 7q = 72pq.........(2)$

$multiply \: in \: equation(1) \: by \: 5 \: and \: (2) \: by \: 2$

$10p - 15q = 20pq......(3)$

$10p + 14q = 144pq........(4)$

$\: \: adding \: equation(3) \: and \: (4)$

$29q = 164pq$

$\frac{29}{164} = p$

put in first equation u get urs answer perfectly
