Solving Rational Equations Quiz Questions Overview
1. What is the first step in solving the rational equation \( \frac{2x}{x-3} = \frac{4}{x+2} \)?
Cross-multiply to eliminate the fractions
Add the fractions together
Subtract \( \frac{4}{x+2} \) from both sides
Multiply both sides by \( x-3 \)
2. Which of the following is a solution to the rational equation \( \frac{x+1}{x-2} = 3 \)?
x = 1
x = 2
x = 5
x = -1
3. What must be done to the equation \( \frac{3x}{x+4} – \frac{2}{x+4} = 1 \) before solving?
Find a common denominator
Cross-multiply
Add 2 to both sides
Subtract 1 from both sides
4. Which of the following is NOT a valid step in solving \( \frac{5}{x+1} + \frac{3}{x-1} = 2 \)?
Cross-multiplying the entire equation
Finding a common denominator
Multiplying both sides by \( (x+1)(x-1) \)
Adding the fractions directly
