Question 1162986
.
<pre>


First, add the two given equations.

The terms "x"  and  "-x"  will cancel each other, and you will get


    -4y = -8;   hence,  y = {{{(-8)/(-4)}}} = 2.


Substitute the found value y= 2 into the second equation.  You will get then


    -x + 2 = 4;   hence,  -x = 4-2 = 2,   or  x = -2.


<U>ANSWER</U>.  x= -2;  y= 2.

Solved.
