# Question #0d9c1

Mar 31, 2017

The answer is $x = y = 3.$

#### Explanation:

This is how we solve this question using elimination method:-

$x + 7 y = + 24 \ldots \left(i\right)$
$x - 9 y = - 24. . . \left(i i\right)$

equation (i)- equation (ii) gives
$\textcolor{w h i t e}{\ldots \ldots} 16 y = 48$
$\textcolor{w h i t e}{. .} \implies y = 3$

Putting $y = 3$ into (i) we get
$x + 21 = 24$
$\implies x = 3$

Therefore, $x = y = 3$.
