Solving 2-Step Word Problems

The video tutorial covers solving two-step equations using word problems. It begins with an introduction to defining variables and setting up equations in the form ax + b = c. The instructor provides four examples: a farmer's market, a cookie jar, a car savings plan, and a balloon delivery service. Each example demonstrates how to define variables, set up equations, and solve them step-by-step. The tutorial emphasizes the importance of showing work and checking solutions.

What is the first step in solving a two-step equation?

• Add a constant to both sides

• Define the variable

• Divide both sides by a number

• Multiply both sides by a number

What is the equation for the cookie jar problem?

• 2x + 32 = 14

• 32 - 2x = 14

• 32 + 2x = 14

• 2x - 32 = 14

How do you solve for x in the equation 32 - 2x = 14?

• Divide both sides by 2

• Add 32 to both sides

• Subtract 32 from both sides

• Multiply both sides by 2
