Solving Equations with Fractions
Solve Solving Equations with Fractions in Grade 10 algebra: use inverse operations and balanced-equation methods to isolate variables with Saxon Algebra practice.
Key Concepts
To solve an equation containing fractions, eliminate the fractions by multiplying every term in the equation by the least common denominator (LCD) of all the fractions. This transforms the equation into one with only integers.
For $\frac{1}{3}x + 2 = \frac{3}{4}x$, the LCD of 3 and 4 is 12. Multiply every term by 12.|The equation becomes $12(\frac{1}{3}x) + 12(2) = 12(\frac{3}{4}x)$, which simplifies to $4x + 24 = 9x$.|To solve $4x + 24 = 9x$, subtract $4x$ from both sides to get $24 = 5x$, so the solution is $x = \frac{24}{5}$.
Fractions in an equation can seem intimidating, but you have a secret weapon: the least common denominator (LCD). Find the LCD of all the fractions in the problem and multiply every single term by it. This clever trick will magically clear away all the denominators, leaving you with a much simpler integer based equation that you can easily solve.
