    Answer:

    (x, y) = (-7, 7)

    Step-by-step explanation:

    y= 7

    -3 – 2x = 7

    Substitute the given value of y into the equation

    – 3x – 2 x 7 = 7

    Solve for the equation for x

    x = -7

    The possible solution of the system is the ordered pair (x, y)

    (x, y) = ( -7, 7)

    Check if the given ordered pair is the solution of the system of equations

    7= -3x (-7) – 2 x 7 = 7

    = 7 = 7 = 7

    Answer:

    x = -3

    (-3,7)

    Step-by-step explanation:

    y = –3x – 2,

    y = 7

    We know the value of y, y=7

    Substitute into the first equation

    7 = –3x – 2

    Add 2 to each side

    7+2 =  –3x – 2+2

    9 = -3x

    Divide each side by -3

    9/-3 = -3x/-3

    -3 = x
