    x = 7, y = 2

    Step-by-step explanation:

    To use the substitution method, we can that the value of "x" (4y - 1) and plug that into the second equation to find "y":

    x + 2y = 11

    (4y - 1) + 2y = 11

    6y - 1 = 11

    6y = 12

    y = 2

    Then we can plug the value of "y" into the first equation to get "x":

    x = 4y - 1

    x = 4 (2) - 1

    x = 8 - 1

    x = 7
