**drwls**, Wednesday, March 10, 2010 at 7:50amI will assume that you mean

6/(z+8) = 5/(z-3)

Parentheses are very important when you write equations on a single line, as here.

Cross multiply to get

6z - 18 = 5z + 40

Now combine terms

z = 58

You could look for an LCM, but that step is not necessary. The answer would be the same.

6 = 5

z+8 4+x

is that the same as what i put earlier?
