anonymous · Answer

ohhh not sure on the first one but for the second one

i rearranged them so the equations looked like this:
4y=x+8
2y=3x-6
can you see how i got that?

anonymous · Answer

Yes

anonymous · Answer

i would then try to isolate one of the Ys.
4y=x+8 would turn into
y=x+2. then plug it in.

2(x+2)=3x-6
do distruibutive property
2x+4=3x-6
-2x    -2x

4=x-6
 +6     +6

10=x

anonymous · Answer

OK!

anonymous · Answer

Then plug in the answer to any equation you want.
you got it from there?

anonymous · Answer

Yes thank you

anonymous · Answer

welcome.

anonymous · Answer

Wait, what do you mean by pluf in the answer int o any equation?

anonymous · Answer

I mena plug in the answer to any equaiton

anonymous · Answer

So like 3(10) + 2y = 6 
Y wasn't found?
