    Answer:

    Step-by-step explanation:

    Example 1:

    Evaluate the following expression:

    4 + (3x +y)

    When x = 2 and y = 9

    3 x 2 is 6 after that you just add 6+9+4 which is 19

    Example 2:

    Evaluate the expression when x=8 and y=9

    x(y – 9)^3 + 2

    =8(9-9)^3+2

    =8(0)^3+2

    =8(0)+2

    =0+2

    =0

    I hope this helps 🙂
