Exploring Adding and Subtracting Rational Expressions

The video tutorial introduces algebraic proportions, explaining the steps to solve them using cross-multiplication. It provides examples, demonstrating how to handle equations with variables on both sides and the use of the distributive property. The tutorial includes a series of odd-numbered problems solved by the teacher, with even-numbered problems assigned to students for practice.

What is the first step in solving algebraic proportions?

• Cross-multiply the fractions

• Subtract the variables

• Distribute the terms

• Solve the two-step equations
