Hi,
I'm stuck at this problem that i'm doing:
4/5x-1 = -9/10x+4
How to do this?
Thanks in advance.
Is your equation:
$\displaystyle \dfrac{4}{5x-1} = \dfrac{-9}{10x+4}$ or is it $\displaystyle \dfrac{4}{5x}-1 = \dfrac{-9}{10x}+4$
For the first, just cross multiply to get rid of the fractions. For the second one, multiply everything by 10x to get rid of the fractions.
