    x = - 1, y = 1

    Step-by-step explanation:

    Solve the following system:

    {5 x + 3 y = - 2 | (equation 1)

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

    Subtract 3/5 * (equation 1) from equation 2:

    {5 x + 3 y = - 2 | (equation 1)

    0 x+y/5 = 1/5 | (equation 2)

    Multiply equation 2 by 5:

    {5 x + 3 y = - 2 | (equation 1)

    0 x+y = 1 | (equation 2)

    Subtract 3 * (equation 2) from equation 1:

    {5 x+0 y = - 5 | (equation 1)

    0 x+y = 1 | (equation 2)

    Divide equation 1 by 5:

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

    0 x+y = 1 | (equation 2)

    Collect results:

    Answer: {x = - 1, y = 1
