    (1, 3)

    Step-by-step explanation:

    Solve the following system:

    {y - x = 2 | (equation 1)

    {x + y = 4 | (equation 2)

    Add equation 1 to equation 2:

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

    {0 x+2 y = 6 | (equation 2)

    Divide equation 2 by 2:

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

    {0 x+y = 3 | (equation 2)

    Subtract equation 2 from equation 1:

    {-x+0 y = - 1 | (equation 1)

    {0 x+y = 3 | (equation 2)

    Multiply equation 1 by - 1:

    {x+0 y = 1 | (equation 1)

    {0 x+y = 3 | (equation 2)

    Collect results:

    Answer: x = 1, y = 3
