| 2 x - 3 | \leq - 1

$| 2 x - 3 | \leq - 1$

Step 1

Since

| 2 x - 3 |

$| 2 x - 3 |$ is always positive and

- 1

$- 1$ is negative,

| 2 x - 3 |

$| 2 x - 3 |$ is always greater than

- 1

$- 1$ so the inequality cannot be true.

No solution

Step 2

⎡ ⎢ ⎣ \begin{matrix} x^{2} & \frac{1}{2} \sqrt{π} & \int x d x \end{matrix} ⎤ ⎥ ⎦

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
