The inequality given in the image is:

$2 \left|\frac{x}{x-1}\right| \leq \left|\frac{x-2}{x+1}\right|$

To solve this inequality, let's break it down step by step.

Step 1: Consider the nature of absolute values.

Absolute values make the inequality hold for both positive and negative cases of the expressions inside them. Therefore, we need to consider different cases based on the expressions inside the absolute values.

Step 2: Identify critical points.

The expressions inside the absolute values change behavior at certain points:

1. $\frac{x}{x-1}$ changes sign at $x = 0$ and $x = 1$ (where the denominator becomes 0).
2. $\frac{x-2}{x+1}$ changes sign at $x = 2$ and $x = -1$ (where the denominator becomes 0).

These points divide the number line into several intervals. We will consider each interval separately.

Step 3: Analyze each interval.

The intervals are:

• Interval 1: $x < -1$
• Interval 2: $-1 < x < 0$
• Interval 3: $0 < x < 1$
• Interval 4: $1 < x < 2$
• Interval 5: $x > 2$

We will evaluate the inequality on each interval by removing the absolute value symbols and considering the sign of the expressions within those intervals.

Interval 1: $x < -1$

• Both $\frac{x}{x-1}$ and $\frac{x-2}{x+1}$ are negative, so: $2 \left|\frac{x}{x-1}\right| = 2\left(-\frac{x}{x-1}\right) = \frac{-2x}{x-1}, \quad \text{and} \quad \left|\frac{x-2}{x+1}\right| = -\frac{x-2}{x+1}$ The inequality becomes: $\frac{-2x}{x-1} \leq -\frac{x-2}{x+1}$

Interval 2: $-1 < x < 0$

• $\frac{x}{x-1}$ is negative, and $\frac{x-2}{x+1}$ is positive, so: $2 \left|\frac{x}{x-1}\right| = \frac{-2x}{x-1}, \quad \text{and} \quad \left|\frac{x-2}{x+1}\right| = \frac{x-2}{x+1}$ The inequality becomes: $\frac{-2x}{x-1} \leq \frac{x-2}{x+1}$

Interval 3: $0 < x < 1$

• $\frac{x}{x-1}$ is negative, and $\frac{x-2}{x+1}$ is positive, so: $2 \left|\frac{x}{x-1}\right| = \frac{-2x}{x-1}, \quad \text{and} \quad \left|\frac{x-2}{x+1}\right| = \frac{x-2}{x+1}$ The inequality becomes: $\frac{-2x}{x-1} \leq \frac{x-2}{x+1}$

Interval 4: $1 < x < 2$

• Both $\frac{x}{x-1}$ and $\frac{x-2}{x+1}$ are positive, so: $2 \left|\frac{x}{x-1}\right| = \frac{2x}{x-1}, \quad \text{and} \quad \left|\frac{x-2}{x+1}\right| = \frac{x-2}{x+1}$ The inequality becomes: $\frac{2x}{x-1} \leq \frac{x-2}{x+1}$

Interval 5: $x > 2$

• Both $\frac{x}{x-1}$ and $\frac{x-2}{x+1}$ are positive, so: $2 \left|\frac{x}{x-1}\right| = \frac{2x}{x-1}, \quad \text{and} \quad \left|\frac{x-2}{x+1}\right| = \frac{x-2}{x+1}$ The inequality becomes: $\frac{2x}{x-1} \leq \frac{x-2}{x+1}$

Step 4: Solve the inequality in each interval.

Solving these inequalities will involve simplifying the expressions and testing for equality or inequality within each interval.

Summary:

We would simplify and solve the inequalities separately within each interval and then combine the results to obtain the final solution for $x$.
