    Step-by-step explanation:

    Start by removing the brackets.

    Left Brackets

    30 (1/2 x - 2)

    30*1/2 x - 30*2

    15x - 60

    Right Bracket

    40 (3/4 y - 4)

    40*3/4 y - 4*40

    10*3 y - 160

    30y - 160

    Now put these 2 results together.

    15x - 60 + 30y - 160 Combine the like terms.

    15x + 30y - 220 That's one answer Others are possible.

    5 (3x + 6y - 44)
