WebExample 2: Solve the compound inequality 2 + 3x > - 10 and 2\left( {x - 1} \right) < x + 4.Graph the solution set on the number line. Then, write the solution set in the interval notation. STEP 1. Solve each inequality. First inequality: 2 + 3x > - 10 Subtract both sides of the inequality by 2.Then divide both sides by 3.. 2 + 3x > - 10 WebWith interval notation, we use use round parentheses, ( or ). With inequalities, we use "less than or equal to": ≤ or "greater than or equal to": ≥ to include the endpoint of the interval. With interval notation, we use use square brackets, [ or ]. To combine two intervals, use U (an uppercase letter u) for union: ∪ ∪.
