i need help with rational expressions!
1/x = 2/x-3
You have an equation, rather than a rational expression. Next, which do you mean?
1/x = 2/x-3 means \(\displaystyle \frac{1}{x} = \frac{2}{x}-3\)
1/x = 2/(x-3) means \(\displaystyle \frac{1}{x} = \frac{2}{x-3}\)
If you want to solve for x, multiply both sides of the equation by the least common denominator of all fractions in the equation. Then solve for x.
