5(x-3) - 2(x) = x(x-3)

5x-15-2x = x^2 -3x

3x-15 = x^2 -3x

this is where i get stuck please help thanks

**MattsRiceBowl**, Sunday, October 31, 2010 at 7:58amLet's try it differently.

5/x = 2/(x-3)

5x - 15 = 2x

3x = 15

X = 5

so your second line should have been

5x-15-2x = 0

Now you have the same as what MatssRiceBowl has in the method he suggested.
