Linear Equations
Solving an equation means finding values that make a statement true, and valid transformations preserve equality.
What you'll learn
- Interpret an equation as a claim that two sides have equal values.
- Preserve equality by applying the same operation to both sides.
- Solve one-step and two-step linear equations by undoing operations in reverse order.
- Explain why a variable keeps one value while equivalent equations change form.
- Check a proposed solution in the original equation and its story.
