The correct Answer is:
To solve the inequality \( 3x + 5(4 - 3x) > 2 - 4x < 3x - \frac{x}{3} \), we will break it down into two parts and solve each inequality separately. ### Step 1: Solve the first inequality \( 3x + 5(4 - 3x) > 2 - 4x \) 1. Distribute \( 5 \) in the left-hand side: \[ 3x + 20 - 15x > 2 - 4x \] 2. Combine like terms: \[ -12x + 20 > 2 - 4x \] 3. Add \( 4x \) to both sides: \[ -12x + 4x + 20 > 2 \] \[ -8x + 20 > 2 \] 4. Subtract \( 20 \) from both sides: \[ -8x > 2 - 20 \] \[ -8x > -18 \] 5. Divide by \( -8 \) (remember to flip the inequality sign): \[ x < \frac{18}{8} \] \[ x < \frac{9}{4} \] ### Step 2: Solve the second inequality \( 2 - 4x < 3x - \frac{x}{3} \) 1. First, simplify the right-hand side: \[ 3x - \frac{x}{3} = \frac{9x}{3} - \frac{x}{3} = \frac{8x}{3} \] 2. Now, rewrite the inequality: \[ 2 - 4x < \frac{8x}{3} \] 3. Multiply through by \( 3 \) to eliminate the fraction: \[ 3(2) - 3(4x) < 8x \] \[ 6 - 12x < 8x \] 4. Add \( 12x \) to both sides: \[ 6 < 20x \] 5. Divide by \( 20 \): \[ \frac{6}{20} < x \] \[ \frac{3}{10} < x \] ### Step 3: Combine the results Now we have two inequalities: 1. \( x < \frac{9}{4} \) 2. \( \frac{3}{10} < x \) This means: \[ \frac{3}{10} < x < \frac{9}{4} \] ### Step 4: Check the options We need to check which of the given options (0, 2, 3, 4) fall within this range. - **Option 0**: \( 0 \) is not greater than \( \frac{3}{10} \). - **Option 2**: \( 2 \) is greater than \( \frac{3}{10} \) and less than \( \frac{9}{4} \) (which is \( 2.25 \)). - **Option 3**: \( 3 \) is greater than \( \frac{9}{4} \). - **Option 4**: \( 4 \) is greater than \( \frac{9}{4} \). Thus, the only value that satisfies both inequalities is \( 2 \). ### Final Answer: The value of \( x \) is \( 2 \). ---
