Inequalities Solution Ea4B27
1. **State the problem:** Solve the system of inequalities:
$$2 \geq 1 - 2x + 3 < 4x$$
$$-1 - 3x \leq 1 - 8x$$
$$4x \leq 2x + 8$$
2. **Solve the first compound inequality:**
Rewrite the first inequality as two parts:
$$2 \geq 4 - 2x$$
$$4 - 2x < 4x$$
- For $$2 \geq 4 - 2x$$:
$$2 - 4 \geq -2x$$
$$-2 \geq -2x$$
Divide both sides by $$-2$$ (remember to reverse inequality):
$$1 \leq x$$
- For $$4 - 2x < 4x$$:
$$4 < 6x$$
$$\frac{4}{6} < x$$
$$\frac{2}{3} < x$$
Combining both parts:
$$x \geq 1$$ (since $$1 > \frac{2}{3}$$)
3. **Solve the second inequality:**
$$-1 - 3x \leq 1 - 8x$$
Add $$8x$$ to both sides:
$$-1 + 5x \leq 1$$
Add $$1$$ to both sides:
$$5x \leq 2$$
Divide by 5:
$$x \leq \frac{2}{5}$$
4. **Solve the third inequality:**
$$4x \leq 2x + 8$$
Subtract $$2x$$ from both sides:
$$2x \leq 8$$
Divide by 2:
$$x \leq 4$$
5. **Combine all solutions:**
From step 2: $$x \geq 1$$
From step 3: $$x \leq \frac{2}{5}$$
From step 4: $$x \leq 4$$
The second inequality requires $$x \leq \frac{2}{5}$$, but the first requires $$x \geq 1$$.
Since $$1 > \frac{2}{5}$$, there is no overlap between these two inequalities.
Therefore, the system has **no solution** where all inequalities hold simultaneously.
**Final answer:**
$$\boxed{\text{No solution}}$$
