Understanding Equivalent Equations

The video tutorial explains how to create equivalent equations by performing the same operations on both sides of an equation. Starting with x = -3, the tutorial demonstrates multiplying by 4, subtracting 5, dividing by 3, and adding 8 to both sides, resulting in equivalent equations. The final step involves verifying that x = -3 is a solution to all these equations, confirming their equivalence.

What is the definition of equivalent equations?

• Equations that have the exact same solution.

• Equations that have infinite solutions.

• Equations that have different solutions.

• Equations that have no solutions.
