What you’ll learn
Given a one-variable equation and a specified finite set of candidate values, explain that a solution is a value that makes the two sides equal and identify which candidates must be tested.
Key idea
A solution is a value that makes both sides equal.
Worked example
Is the candidate value a solution of the equation?
2x = -2
Replace x with the candidate and compare the two exact values.
Solution
Answer: Solution
