Guided Notes
Key concepts students will learn:
- •
To solve an equation with fractions, you can multiply both sides by the least common denominator to clear the fractions.
- •
When solving the equation 2/9x - 1 = 2/3x - 2, multiplying both sides by 9 will eliminate the fractions.
- •
After solving the equation and getting x = 9/4, you can substitute this value back into the original equation to check your answer.
