    X=1/6 Y=0

    Step-by-step explanation:

    If Y = 6x-1, substitute Y on the first equation

    7x+3 (6x-1) = 7/6

    7x+18x-3=7/6

    25x = (7/6) + 3

    25x=25/6

    x=1/6

    Then substitute X on the second equation

    Y=6 (1/6) - 1

    Y=0

    x = 1/6

    y = 0

    Step-by-step explanation:

    7x+3 (6x-1) = 7/6 Substitute in.

    7x+18x-3 = 7/6 Distributive Property.

    25x = 25/6 Isolate the variable.

    x = 1/6 Divide by 25.

    y = 6 (1/6) - 1 Substitute in.

    y = 1-1 Multiply.

    y = 0 Subtract.
