Question

which statements are true about the ordered pair (-1,5) and the system of equations x+y=4 x-y=-6​

2 Answer

  • Answer:

    A) x+y=4

    B) x-y=-6​

    We add both equations and get

    2x = -2 so x = -1

    and y = 5

    So the ordered pair (-1, 5) is the solution to the equations.

    Step-by-step explanation:

  • -1+5=4
    And
    -5+1=-4
    So it’s x+y=4
