algebraSolve for :
A
B
C
D
Correct Answer: A
Choice A is the correct answer. This two-step inequality requires both subtraction and division.
- Subtract 5: , giving
- Divide by 2: , giving
- Verify: Try : ??n ?�� Strategic Tip: Two-step inequalities follow the same order as two-step equations: first eliminate the constant, then eliminate the coefficient.
Choice B is incorrect because it reverses the inequality direction without justification (we divided by positive 2, which doesn't reverse the sign). Choice C is incorrect because it adds 5 and 13 to get 18, then halves it, using faulty logic. Choice D is incorrect because it combines the wrong value (9) with the wrong direction (<).
