Solving Two-Step Equations Made Easy

The video tutorial covers solving two-step equations using algebra tiles and inverse operations. It includes examples like solving 3n + 2 = 11, 2x + 5 = 11, and equations with negative numbers. Real-world problems, such as calculating the original weight of a sled and converting temperatures, are also addressed. The tutorial emphasizes the importance of maintaining balance in equations and using inverse operations to isolate variables.

What is the first step in solving the equation 3n + 2 = 11 using algebra tiles?

• Add 2 to both sides

• Subtract 2 from both sides

• Multiply both sides by 3

• Divide both sides by 3
