    Answer: x = - 19

    y = 55

    Step-by-step explanation:

    y = - 3x - 2 (1)

    5x + 2y = 15 (2)

    substitute y = - 3x - 2 into equation (2)

    equation (2) becomes

    5x + 2 (-3x - 2) = 15

    5x + ( - 6x - 4) = 15

    opening the bracket

    5x - 6x - 4 = 15

    collecting like terms

    5x - 6x = 15 + 4

    -x = 19

    x = - 19

    substituting x = - 19 into equation 1

    y = - 3x - 2

    y = - 3 (-19) - 2

    y = 57 - 2

    y = 55
