- Concept review and examples of Algebraic Proofs in the context of Logic and Proof. Skip to navigation But the square root of 25 is 5, so where's the problem? Well, z = 5 is only one of the answers. Couldn't z = -5 be an answer too? Yes, it could. That's what the proof didn't consider. Show Next Step. Example 3. Write a proof for the statement "If x 3 + y = 10 and 3(3x â€“ 3) = 9, then x
- When you are attempting to solve an equation algebraically and you end up with an obvious identity (like 3 = 3), then you know that the original equation must also be an identity, and therefore it has an infinite number of solutions.
