Oh, derp. I should've figured that out when the "equation" only had one side... x_x

Have you people not learned this before? I mean, even I learned this in my 9th year. Though I still suck at this.

Edit: I'm Canadian, if that matters.

You need to use parentheses for these problems or take a picture of the problems. It's pretty much impossible to give you the right answer when you don't specify what's being divided, multiplied, added or subtracted by what.

I'm in 10th Grade, but I suck at this. But I'll try to help ya:

1) x+y/x+z= yz (x/x=1?)

2)xa+xb/x+xd=ab+d (Just guessing.)

3)1/1-x/y= (-x/y) <~ That's a negative.
