Solving Equations and Word Problems

The video tutorial introduces the concept of solving equations, emphasizing the goal of isolating the variable. It outlines four key steps: performing opposite operations, maintaining equality by applying changes to both sides, and verifying solutions with a check step. The tutorial provides examples, including solving x + 5 = 13, and highlights common mistakes. It also covers converting verbal phrases into equations and solving word problems, using a taco example to illustrate the process.

What is the primary goal when solving an equation?

• To isolate the variable

• To find the value of the constant

• To balance both sides with the same number

• To eliminate all numbers

What is the opposite operation of addition?

• Division
