Solve the system by graphing. Please show correct graph if possible

The solution set is { }

(Type an ordered pair.)

Solution

x-y=-7 .......(1)

x+y=1 ..........(2)

Add equation (1) and (2) we get

2x=-6

x= -6/2 = -3

substitute this value of x in equation (1) we get

-3-y = -7

-y = -7+3

-y = -4

y=4

Hence the solution set is {-3, 4}
