    x = 2/51, y = 104/51

    Step-by-step explanation:

    Solve the following system:

    {53 x - 2 y = - 2 | (equation 1)

    y - x = 2 | (equation 2)

    Add 1/53 * (equation 1) to equation 2:

    {53 x - 2 y = - 2 | (equation 1)

    0 x + (51 y) / 53 = 104/53 | (equation 2)

    Multiply equation 2 by 53:

    {53 x - 2 y = - 2 | (equation 1)

    0 x+51 y = 104 | (equation 2)

    Divide equation 2 by 51:

    {53 x - 2 y = - 2 | (equation 1)

    0 x+y = 104/51 | (equation 2)

    Add 2 * (equation 2) to equation 1:

    {53 x+0 y = 106/51 | (equation 1)

    0 x+y = 104/51 | (equation 2)

    Divide equation 1 by 53:

    {x+0 y = 2/51 | (equation 1)

    0 x+y = 104/51 | (equation 2)

    Collect results:

    Answer: x = 2/51, y = 104/51
