Choose the correct solution of (3(2x-1)-2(x+5)\le x+4).

Answer and explanation

Correct answer: x\le\frac{17}{3}

This is solved using the distributive property followed by the rules for a linear inequality. Expand the left side: 3(2x-1)-2(x+5)=6x-3-2x-10=4x-13. The inequality therefore becomes 4x-13\le x+4. Subtracting x gives 3x-13\le4, and adding 13 gives 3x\le17. Since 3 is positive, division preserves the sign and yields x\le17/3. Thus option C is correct. The boundary value 17/3 is included because the original sign is ‘less than or equal to’. Option A stops before dividing by the coefficient 3, option B reverses the direction and uses the boundary as a lower bound, and option D has both an incorrect direction and an incorrect scale.
