Solve the inequality (3-\frac{x+2}{5}<1).

Answer and explanation

Correct answer: (x>8)

The direct answer is A: x>8. Begin with 3−(x+2)/5<1. Subtract 3 from both sides: −(x+2)/5<−2. Multiply both sides by 5, which is positive: −(x+2)<−10. Now multiply by −1, or divide by −1. Because this number is negative, reverse the sign: x+2>10. Subtract 2: x>8. Option A is correct. Option B, x<8, has the inequality direction reversed incorrectly; the negative factor requires reversal in the opposite way. Option C, x>−8, has the wrong boundary and may result from mishandling the +2. Option D, x<−8, has both the wrong boundary and wrong direction. Testing x=9 gives 3−11/5=0.8<1, so it works. Testing x=8 gives 1, not a strict value below 1, so x=8 is excluded. Testing x=7 gives 1.4, which fails. Memory cue: whenever you remove a negative coefficient, reverse the inequality sign; with <, the boundary itself is not included.
