    We have the following system:

    y = - 2x + 5

    3x-4y = 2

    Substituting y in equation 2 we have:

    3x-4 (-2x + 5) = 2

    We clear x:

    3x + 8x - 20 = 2

    11x = 2 + 20

    x = 22/11

    x = 2

    Then, we substitute x = 2 in equation 1:

    y = - 2 (2) + 5

    y = - 4 + 5

    y = 1

    Answer:

    The solution to the system of equations is:

    x = 2

    y = 1
