2x-y=-5
-2x-5y=11

  • 10th grade - ,

    Eq1: 2x - y = -5
    Eq2: -2x - 5y = 11

    Add the 2 Eqs and get:
    -6y = 6,
    Divide both sides by -6:
    y = 6 / -6 = -1.

    Substitute -1 for y in Eq1:
    2x - (-1) = -5,
    2x + 1 = -5,
    2x = -5 -1,
    2x = -6,
    Divide both sides by 2:
    x = -6 / 2 = -3.

    Solution set: (-3 , -1).
