    x=1

    y=0

    Step-by-step explanation:

    x+3y = 1 equation 1

    -5x+4y = - 5 equation 2

    using equation 1 we have:

    x+3y = 1

    x = 1-3y equation 3

    using equation 3 in equation 2 we have:

    -5 (1-3y) + 4y = - 5

    -5 + 15y + 4y = - 5

    19y - 5 = - 5

    19y = - 5 + 5

    19y = 0

    y=0

    so we have:

    x = 1-3y

    x = 1 - 3 (0)

    x=1
