Example: Solving
To solve the absolute value inequality , 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: or . Step 3 involves independently solving these generated inequalities. Adding to both sides of both expressions reduces them to or , and subsequently dividing each by yields the final algebraic solution of or . Step 4 is to accurately graph the solution on a standard number line, physically represented by a closed circle on with shading stretching to the left, alongside a completely separate set starting with a closed circle on continuing rightward. Step 5 dictates expressing this dual, non-overlapping solution correctly utilizing formal interval notation, recorded as .
