Mrs. Angel teaches students how to solve tougher two-step equations by identifying terms, coefficients, and using properties of equality. The lesson covers solving equations with single terms that are products or quotients, and demonstrates step-by-step solutions for two example equations. Students are encouraged to practice solving similar equations and understand the importance of creating zero terms and big one factors. The lesson concludes with a recap of the key concepts and methods used.

What makes a two-step equation tougher compared to a regular two-step equation?

• It has more than two terms.

• The constant and variable term are grouped together.

• It involves only addition and subtraction.

• It has no coefficients.
