Answer 1

question:

x-y=-6

x+y=8

Step-by-step explanation:

   x-y=-6  add the equations

+  x+y=8

2x     =2

   2x=2 solve for x

     x=1

x+y=8 substitute x=1 into one of the original equations and solve for y

1+y=8

y=8-1

   y=7

x-y=-6                               x+y=8

1-7=-6                                1+7=8

   -6=-6                                 8=8

the solution is (1,7) as x was 1 and y was 7.
