You would multiply both 2x and -8 by 5. The answer would be 10x-40.
You can think of this equation as

and thus apply the transformations to it as such



1) D = 2, C = +3
2) D = -12, C = -2
3) C = +6, D = 3
4) C = -7, D = -7
set up a proportion. you have 60/100 and 27/x
now you do 27x100=2700 then divide that by 60
with a calculator you get 45
then you can check your answer by saying 60% of 45 and you get 27 Samuel has 45 toy cars in total
Distribute -4 in this way:
-4(2x) - 4(-1) > 5 - 3x, to get
- 8x + 4 > 5 - 3x

At the beginning, Malik had 33 beads, and Eric had 44, making them have 77 beads in total
At the end, Malik had (33 + 13 =) 46 beads and Eric had (44 + 48 = ) 92 beads.
