Single Variable Equations

Sample Lessons – Over view of Equations

2 Lessons

What is a single variable equation?

What is an algebraic expression, an equation and a solution?

Unit 1 – Simple one step equations

5 Lessons

Solve an equation when a number is added to the variable ( Example : x + 21 = 78)

Solve an equation when a number is subtracted from the variable ( Example : x- 21 = 78)
