Understanding One-Step Inequalities

One-step inequalities are algebraic inequalities that can be solved in a single step. They involve comparing an algebraic expression to a value using inequality symbols like <, >, ≤, or ≥. For subtraction inequalities of the form x - a ? b, we isolate x by adding a to both sides of the inequality.

For example, to solve x - 3 < 5, we add 3 to both sides: x < 5 + 3, which simplifies to x < 8. This means any value of x less than 8 satisfies the inequality. The number line visualization helps to graphically represent this solution set.
