get a common denominator ...
... note that (why?)
all denominators are common, the numerators form the equation
finish it.
Please help me with my homework, I've been solving it from 4 hours and everything is wrong. I just cant get the same answer that the back of the book has.
1. Solve equations.
a)
\frac{x}{3-x}+ 3=\frac{5}{2x-6}
b)
\frac{4}{2x^2+x}- \frac{6x}{2x+1}= 1
2.transform to canonical form
f(x)=\frac{x+3}{x+2}
f(x)=\frac{2x}{x-1}
