    Same way you solve a normal equation, but if you multiply or divide by a negative number, you have to switch the direction of the inequality symbol.

    add 3 to both sides = -2x ≥ 24 , now divide by -2 to isolate x , giving you x LESS THAN OR EQUAL TO (sign flips when dividing by negatives) -12

    -2x - 3 -2x - 3 ≥ 21 21 Add 3 to both sides +3 +3 ------------ -2x ≥ 24 Divide by - 2 /-2 /-2 --------- x ≥ 12
