Solve the inequality 5 - 2x > 1.
Answer and explanation
Correct answer: D. x < 2
- Step 1: Subtract 5 from both sides: -2x > -4. Step 2. Divide by -2 and reverse the sign: x < 2. Answer: x < 2. Why not the others: x > 2 forgets to reverse the sign; x < -2 and x > -2 get the sign of the value wrong.
