Solving 2 Step Equations with Algebra Tiles

Dirk from Made for Math introduces solving two-step equations using a multi-sensory approach. The video explains the concept of isolating variables and demonstrates solving an equation using manipulatives. The process involves identifying operations affecting the variable, performing opposite operations, and verifying the solution.

What is the primary goal when solving equations as discussed in the video?

• To perform all mathematical operations

• To isolate the variable

• To multiply the constants

• To add all numbers
