    (2, 5)

    Step-by-step explanation:

    plug the numbers into the equations

    or

    rearrange the top equation to be y = - 5 + 5x

    plug this in for y in the second equation.

    -4x + 2 (-5 + 5x) = 2

    solve for x

    -10 + 6x = 2

    6x = 12

    x = 2

    plug this into one of the equations to get y

    -5*2 + y = - 5

    -10 + y = - 5

    y = - 5 + 10

    y = 5
