x/8=-6

-4/9+(-5/7)

x-4/5=6/7

7/x=?/xsquared

**drwls**, Friday, April 11, 2008 at 9:32am1.Multiply both sides of the first equation by 8

2. convert each fraction to have a (common) denomiator of 63. Then add the numerators

3. Multiply both sides of the equation by 35 and yet 7(x-4) = 30

Then solve that.

4. I assume you mean (7/x) = y/x^2

where y is a new unknown that you indicate by ?

xy = 7x^2

y = 7x
