Answer 23

aweeeeeee

Answer 24

wait ima so stupid

Answer 25

I started by adding 27 to both sides.

Answer 26

lol i thought u did right srry i didnt check cause @AlexandervonHumboldt2 already did it on top

Answer 27

sorry let me start as i did:

Answer 28

v + c = 27
4v + c = 45

=> c=27-v c=45-4v

=> 45-4v=27-v
v=6

thus: c=27-6=21

thus 6 and 21

Answer 29

yeah sorry you was correct

Answer 30

*were

Answer 31

lol willie

Answer 32

Oh, so 24 = v is correct?

Answer 33

yes it is , i got 24 too

Answer 34

u just plug into any eq v=24

Answer 35

Okay so for example, v + c = 27
I would do it like this, 24 + c = 27
Subtract 24 from both sides, which means c = 3?

Answer 36

Do we all agree?

yes well done
