I need help with this elimination problem
nataly862011 [7]

Add up the same sides of both equations to eliminate <em>x</em> :

(<em>x</em> - 2<em>y</em>) + (-<em>x</em> + 3<em>y</em>) = 8 + (-5)

(<em>x</em> - <em>x</em>) + (-2<em>y</em> + 3<em>y</em>) = 8 - 5

<em>y</em> = 3

Then

<em>x</em> - 2<em>y</em> = <em>x</em> - 6 = 8   →   <em>x</em> = 14
