Algebra practice question

Answer: A. x > 5

Divide by 5 first: x − 2 > 3, so x > 5.

Why the other answers are wrong

B. x > 3

3 is the bound on x − 2, not on x; add back the 2.

C. x > 13/5

13/5 comes from adding 2 before clearing the 5 incorrectly; divide first, then add 2.

D. x < 5

Dividing by positive 5 keeps the > direction.
