B15HOPB01 says

so that both why had 24 infront of them… it doesn’t matter that there is a + on one and a – on the other.

RasinDart says

move over the -12 to the 18 when u move over it become + 12 so 18 + 12 give u 30

talhahnesar1 says

why did you multiply equation 1 by 4 and 2 by 3???

superstu86 says

Please please help with how did the guy come up with: 6y=30? The bit before made sense but not from 1:57 mins onwards? I get -12 + 6y =18 but not the bit after that. Where does 6y=30 come from?

masterslyy says

seansk8erandrider says

Nyrax18 says

AlganitTabir says

i got x=6 wtf!

eilatan321 says

help me!

how do you work out:

2x + 3y = 6

3x – 2y + 22

i thought x was 4 because i got 7x +28

but now what do i do?!

i tried to substitute it in but look:

2(4) + 3y = 6

8 + 3y = 6

what the hell?

3y has to be 2 right?

how does that work?

2 divded by 3 will make it really messy right?

im so confused, help me please!
