Solve the inequality −2(x − 4) + 5 < 3(1 − x).

Answer and explanation

Correct answer: x < −10

Use the distributive law carefully on both sides. The left side becomes −2x + 8 + 5 = −2x + 13, while the right side becomes 3 − 3x. Therefore −2x + 13 < 3 − 3x. Add 3x to both sides: x + 13 < 3. Subtract 13: x < −10. No sign reversal occurs in these steps because only terms are being added or subtracted. Hence option D is correct. A quick check with x = −11 gives 35 < 36, which is true, whereas x = −10 gives equality, not a strict inequality, so −10 must be excluded. Option A has the wrong direction, option B includes the invalid endpoint, and option C has the wrong numerical boundary.
