Hi
Solution to the following system:
 x+y=7  
<u>2x-y=2 </u>
 3x = 9, x = 3 and y = 4

2x+y=4 and ||||multiplying 1st EQ thru by 2 to  eliminate the y variable
3x-2y=13
4x+2y=8 and ||||Result of multiplying 1st EQ thru by 2 to  eliminate the y variable
<u>3x-2y=13</u>    
  7x = 21, x = 3  and y = -2   (2x+y = 4 or y = 4-2x)
