Example: Solving 2x35|2x - 3| \geq 5

To solve the absolute value inequality 2x35|2x - 3| \geq 5, follow the five-step systematic procedure for 'greater than' inequalities. Step 1 is to verify the absolute value expression is isolated, which it already is. Step 2 requires writing the equivalent compound inequality: 2x352x - 3 \leq -5 or 2x352x - 3 \geq 5. Step 3 involves independently solving these generated inequalities. Adding 33 to both sides of both expressions reduces them to 2x22x \leq -2 or 2x82x \geq 8, and subsequently dividing each by 22 yields the final algebraic solution of x1x \leq -1 or x4x \geq 4. Step 4 is to accurately graph the solution on a standard number line, physically represented by a closed circle on 1-1 with shading stretching to the left, alongside a completely separate set starting with a closed circle on 44 continuing rightward. Step 5 dictates expressing this dual, non-overlapping solution correctly utilizing formal interval notation, recorded as (,1][4,)(-\infty, -1] \cup [4, \infty).
