Answer:

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.
