    First, let's rearrange the first equation so we can know what y equals to.

    So, (x - y = 2) becomes (y = x - 2).

    Now, we can plug this into the second equation so we can find x.

    6x + 4 (x - 2) = 92

    6x + 4x - 8 = 92

    10x - 8 = 92

    10x = 100

    x = 10

    Now that we know x equals 50, we can plug this into either equations to find y. Let's use the first equation.

    10 - y = 2

    -y = - 8

    y = 8

    Now, let's check our work by plugging int eh values of x and y for both equations.

    First equation:

    10 - 8 = 2

    Second equation:

    6 (10) + 4 (8) = 92

    60 + 32 = 92

    So, the values of x and y are correct.
