\frac{1-3x}{x-2}-\frac{x-2}{x-2}\geq 0
To add or subtract expressions, expand them to make their denominators the same. Multiply 1 times \frac{x-2}{x-2}.
\frac{1-3x-\left(x-2\right)}{x-2}\geq 0
Since \frac{1-3x}{x-2} and \frac{x-2}{x-2} have the same denominator, subtract them by subtracting their numerators.
\frac{1-3x-x+2}{x-2}\geq 0
Do the multiplications in 1-3x-\left(x-2\right).
\frac{3-4x}{x-2}\geq 0
Combine like terms in 1-3x-x+2.
3-4x\leq 0 x-2<0
For the quotient to be ≥0, 3-4x and x-2 have to be both ≤0 or both ≥0, and x-2 cannot be zero. Consider the case when 3-4x\leq 0 and x-2 is negative.
x\in [\frac{3}{4},2)
The solution satisfying both inequalities is x\in \left[\frac{3}{4},2\right).
3-4x\geq 0 x-2>0
Consider the case when 3-4x\geq 0 and x-2 is positive.
x\in \emptyset
This is false for any x.
x\in [\frac{3}{4},2)
The final solution is the union of the obtained solutions.
