    {x, y} = {2,7}

    Step-by-step explanation:

    / / Solve equation [1] for the variable y

    [1] y = - 4x + 15

    / / Plug this in for variable y in equation [2]

    [2] 3x + 5• (-4x+15) = 41 [2] - 17x = - 34

    / / Solve equation [2] for the variable x

    [2] 17x = 34 [2] x = 2

    / / By now we know this much:

    x = 2 y = - 4x+15

    / / Use the x value to solve for y

    y = - 4 (2) + 15 = 7
