Solving Two-Step Equations with Fractions

This video tutorial demonstrates how to solve two-step equations with fractions using two methods. The first method involves clearing fractions by multiplying by the least common denominator, while the second method keeps fractions in the equation. The tutorial provides a step-by-step example, verifies the solution, and compares the two methods, highlighting the advantages of each approach.

What are the two methods discussed for solving two-step equations with fractions?

• Using substitution and elimination

• Keeping fractions and clearing fractions

• Graphing and factoring

• Using matrices and determinants

What is the first step in the method of clearing fractions from an equation?

• Add fractions

• Find the least common denominator

• Subtract fractions

• Divide by the largest fraction

In the example, what is the least common denominator used to clear fractions?

• 20

• 25

• 10

• 15

What is the result of multiplying each term by the least common denominator in the example?

• 60x + 12 = 15

• 3x + 5 = 4

• x + 3 = 5

• 2x + 4 = 6
