WebFind the solution to the linear inequality, -2x - 39 ≥ -15, and plot it on a number line. Solution: We will solve the problem in the following way: - 2x - 39 ≥ - 15 ⇒ - 2x ≥ 24. ⇒ 2x ≤ - 24 ⇒ x ≤ - 12. The linear inequality will be plotted on a number line in the following way: The solution set is plotted above.
