<span>A) -x+y=4
B) 6x+y= -8
Multiplying "A" by -1
A) x -y = -4 then adding it to B
B) 6x + y = -8
7x =-12
x = -12/7 = </span><span>-1.7142857143
y = 4 + x = </span><span><span><span>2.2857142857
</span></span></span>Did you make a typo because as you can see, the solution is not one of the 4 choices.
