Solving Linear Equations Concepts

This video tutorial covers solving one-step equations using addition and subtraction. It explains what constitutes a solution to an equation and demonstrates the principles of equality. The tutorial includes step-by-step examples of solving equations and concludes with a real-world word problem to apply the learned techniques.

What is a solution to an equation?

• Any value that makes the equation false

• Any value that makes the equation true

• Any number that can replace a variable

• Any number that is greater than zero
