Solving 2 Step Equations with Algebra Tiles

The video tutorial explains how to solve two-step equations using a balance model. It begins with solving the equation 2x + 3 = 11 by removing loose items and dividing the remaining items into groups. The tutorial then moves on to solving x/3 - 2 = 1 by adding positives to balance the equation and multiplying to find the value of x. The concept of inverse operations is emphasized throughout the tutorial.

What does the balance represent in the equation 2x + 3 = 11?

• Three boxes and two loose items

• Two boxes and eleven loose items

• Eleven boxes and three loose items

• Two boxes and three loose items
