Question

Solve by graphing and solution

x-y=-4
y=-x+2

Answer 1

The solution is x=-1, y=3

The graph in the attached figure

Explanation:

we have

`x-y=-4` ----> equation A

`y=-x+2` ----> equation B

Solve the system by graphing

Remember that the solution of a system of linear equations by graphing, is equal to the intersection point both graphs

using a graphing tool

The intersection point is (-1,3)

see the attached figure

therefore

The solution is x=-1, y=3
