Question

$3p + 2q = 12 \\ 2p + 3q = 13$
​

Answer 1

Heya,

====================

This type of question can be best answered by a simple method, Add them once and subtract them

====================

$3p + 2q = 12............(1) \\ 2p + 3q = 13.............(2)$

Adding equation (1) and (2), we get

$5p + 5q = 25 \\ = > p + q = 5$

Let us subtract them now

$p - q = - 1$

Now, add this two equations to get

$2p = 4 = \\ p = \frac{4}{2} = 2$

put p = 2 in any these equations to get

$q = 3$

Hence,

p = 2, q = 3.
