ANSWER: 10 x - 200 + 30 y
You will remove them parentheses soon so…
20 ( 1/2 x - 2) + 40 ( 3/4 y - 4)
Distributed 20 through the parentheses
10 x - 40 + 40 (3/4 y - 4)
( this is for 20 ( 1 /2 x - 2) side, now let’s do the other side)
10 x - 40 + 30 y - 160
( this is for 40 (3/4 y -4 side )
Now calculate the difference
10 x - 200 + 30 y
That will be your answer.
