show a simple way of doing this inequaltiy

12 - 2/3x is greater than 6

1 answer

To solve the inequality \( 12 - \frac{2}{3}x > 6 \), follow these steps:

  1. Isolate the variable term: Start by subtracting 12 from both sides.

    \[ 12 - \frac{2}{3}x - 12 > 6 - 12 \]

    This simplifies to:

    \[ -\frac{2}{3}x > -6 \]

  2. Eliminate the negative coefficient: To make the coefficient of \( x \) positive, multiply both sides of the inequality by -1. Remember to flip the inequality sign when you do this.

    \[ \frac{2}{3}x < 6 \]

  3. Solve for \( x \): To get \( x \) by itself, multiply both sides by the reciprocal of \( \frac{2}{3} \), which is \( \frac{3}{2} \):

    \[ x < 6 \cdot \frac{3}{2} \]

    Calculate \( 6 \cdot \frac{3}{2} \):

    \[ 6 \cdot \frac{3}{2} = \frac{18}{2} = 9 \]

  4. Final result: Thus, the solution to the inequality is:

    \[ x < 9 \]

This tells us that \( x \) can take any value less than 9.
