    x = 0

    y = 2

    Step-by-step explanation:

    x + 4y = 8

    4x + y = 2

    Solve for x in first equation.

    x = 8 - 4y

    Put x as 8+4y in the second equation.

    4 (8 - 4y) + 1y = 2

    32 - 15y = 2

    -15y = - 30

    y = 2

    Put y as 2 in first equation.

    x + 4 (2) = 8

    x + 8 = 8

    x = 8 - 8

    x = 0
