Multi–Step Inequalities – Example 1:
Solve this inequality. \(4x-8 > 24\)
Solution:
First add \(8\) to both sides: \( 4x-8 > 24→ 4x-8+8 > 24+8\)
Then simplify: \(4x-8+8 > 24+8→4x > 32\)
Now divide both sides by \(4: \frac{4x}{4} > \frac{32}{4 } →x > 8\)
Multi–Step Inequalities – Example 2:
Solve this inequality. \(2x + 6 \leq10\)
Solution:
First subtract \(6\) from both sides: \(2x + 6 \leq10\) → \(2x+6−6≤10−6\)
Then simplify: \(2x+6−6≤10−6→2x≤4\)
Now divide both sides by \(2: \frac{2x}{2}≤\frac{4}{2} →x≤2\)
Multi–Step Inequalities – Example 3:
Solve this inequality. \(2x-2≤6\)
Solution:
First add \(2\) to both sides: \(2x-2≤6\) → \(2x-2+2≤6+2\)
Then simplify: \(2x-2+2≤6+2→2x≤8\)
Now, divide both sides by \(2: \frac{2x}{2}≤\frac{8}{2}→x≤4\)

Multi–Step Inequalities – Example 4:
Solve this inequality. \(-2x-4 < 8\)
Solution:
First add \(4\) to both sides: \(-2x-4 < 8\) → \(-2x-4+4 < 8+4\)
Then simplify: \(-2x-4+4 < 8+4→-2x < 12\)
Now divide both sides by \(-2\) (Remember, for dividing or multiplying both sides by negative numbers, flip the direction of the inequality sign.)
\(\frac{-2x}{-2} > \frac{12}{-2 } →x > -6\)
