Can someone solve this and show the work for me, please?

3(x-y)=2(y-x) + 8

-(2x - y) = 3(y + 3x - 1)

Thanks very much. i\I just need to know how to work it.

hmm...

first let's distribute out the equations to get:

Alright, now let's solve for x (or y, it's your choice) for the first problem:

now take the second equation:

and also solve for x:

and now we can start solving stuff. First things first, you have to write down that:

So now we substitute:

so now multiply both sides by -11 and 5 to get:

now use the distributive property:

now move things around:

then divide:

Now you can solve for x.

On a side note, is not a nice number, you should double check my work and see if my arithmetic is right. - Aug 26th 2008, 05:44 PMJhevon
