Solving One-Step and Two-Step Equations Challenge

The video tutorial explains how to solve equations using the concept of opposites. It covers five examples, starting with simple equations and progressing to more complex ones. The tutorial emphasizes the importance of balancing equations by performing the same operation on both sides. It demonstrates solving equations involving addition, subtraction, multiplication, and division, and concludes with a two-step equation example.

What is the goal when solving equations?

• To multiply all numbers together

• To add all numbers together

• To isolate the variable on one side

• To make both sides of the equation equal
