    The answer to your question is:

    Step-by-step explanation:

    1. - y = 4x + 2

    y = x - 3

    x - 3 = 4x + 2

    4x - x = - 3 - 2

    3x = - 5

    x = - 5/3

    y = - 5/3 - 3

    y = (-5 - 9) / 3

    y = - 14/3

    2. - 7x + 2y = 18

    6x (+) 6y = 0 There is no sign in the second
