    ANSWER: (3,4)
    Explanation: multiply both sides of the equation by -1
    Sum the equations vertically to eliminate at least one variable so you should be left with 6x=18
    Then divide by 6 on both sides
    Substitute the value of x
    Solve the equation
    So you should have 4×3-5y=-8
    Y=4
    Then plug in the values you got, (3,4) into the original systems to see if what the values you got makes the statement true
