(it asked me for 20 word so ignore this text)
Multiply one of them by -1 so one of the -2y is positive
-1(-7x-2y=-13)=7x+2y=13
Then add the two equations
7x+2y=13
+ x-2y=11
========
8x=24 - the 2y and -2y cancel out. Now solve for x
x=3 Now plug the x back into one of the equations
3-2y=11 Now solve for y
-2y=11-3
-2y=8
y=-4
So x=3 and y=-4
Hope this helps!
