    x = - 3, y = - 6

    Step-by-step explanation:

    Given the 2 equations

    - 14x = - 72 - 19y → (1)

    9x = 87 + 19y → (2)

    Add the 2 equations term by term to eliminate the y - term

    - 5x = 15 (divide both sides by - 5)

    x = - 3

    Substitute x = - 3 into either of the 2 equations and evaluate for y

    Substituting into (2)

    9 ( - 3) = 87 + 19y

    - 27 = 87 + 19y (subtract 87 from both sides)

    - 114 = 19y (divide both sides by 19)

    - 6 = y

    Thus x = - 3, y = - 6
