Question

X+y=2 and x+y=-1 solve by graphing please and show the solution

Answer 1

Answer:

The answer to your question is There is no solution, the lines are parallel.

Step-by-step explanation:

Data

Equation 1     x + y = 2

Equation 2    x + y = -1

Solve for y

Equation 1          y = -x +2

                          y = - x + 2

Equation 2         y = - x - 1

See the graph below

These lines do not cross, so there is no solution. They are parallel.

If the lines have crossed, there  would be a solution.
