    Solve the following system using elimination:

    {x - 2 y = - 23 | (equation 1)

    {x - y = 7 | (equation 2)

    Subtract equation 1 from equation 2:

    {x - 2 y = - 23 | (equation 1)

    {0 x+y = 30 | (equation 2)

    Add 2 * (equation 2) to equation 1:

    {x+0 y = 37 | (equation 1)

    {0 x+y = 30 | (equation 2)

    Collect results:

    Answer: {x = 37, y = 30
