Solving One Step Equations: Day 2 Insights

This video tutorial teaches how to solve one-step equations by isolating the variable using opposite operations. It covers the difference between expressions and equations, and provides examples of solving equations by adding, subtracting, multiplying, or dividing. The tutorial concludes with a reminder to bring notes to class for further discussion.

What is the main difference between an expression and an equation?

• An equation contains variables, an expression does not.

• An expression contains an equal sign, an equation does not.

• An equation contains an equal sign, an expression does not.

• An expression contains variables, an equation does not.
