Treat variables as numbers whose value may be unknown and use inverse operations to isolate them.
Review Algebra basics before starting →Ideas to recall
- A variable represents a number that may be unknown or allowed to change.
- Like terms can be combined only when their variable parts match.
- Apply the same valid operation to both sides of an equation.
- Substitute the result into the original equation to check it.
Use these ideas to reason through each question; answer-specific explanations appear only after you check a response.
