Question

X-y=2 and x+y=-2 sove by graphing please and show the solution

Answer 1

Answer:

The answer to your question is There is only one solution (0, -2)

Step-by-step explanation:

Data

Equation 1     x - y = 2

Equation 2    x + y = -2

Solve for y

Equation 1          y = x -2

                          y = x - 2

Equation 2         y = - x - 2

See the graph below

These lines cross in point (0 ,-2), that is the only solution.

If the lines have not crossed, they were parallel lines.
