  1. 1. If you need to refresh your skills click the tutorial button. If you are ready for some practice click the Practice button. If you want to play a game click the games button
  2. 2. Solve the inequalities just like you would an equation. Except when you multiply or divide by a negative to solve you must flip the inequality.
  3. 3. Solve 2x + 3 < 13 Step 1 We have to get the 3 to the Step 2 We have to divide both sides by other side by adding opposite to both 2 to get X by itself since we are dividing sides by a positive we do not have to flip the 2x + 3 < 13 inequality + -3 +-3 yielding 2x < 10 2x < 10 yields x < 5 2 2 Since x is by itself we have successfully solved the inequality Next
  4. 4. Solve -1 x - 5 > 10 2 Step 1 we have to get Step 2 we have to get x by itself by rid of the 5 by multiplying by the reciprocal of – 1 adding the opposite Which is -2 2 to both sides -1 x - 5 > 10 -2 * -1 x > 15 * -2 2 +5 +5 2 Since we multiplied by a negative we have to flip the inequality Yields -1 x > 15 2 X < - 30 Prev Next
  5. 5. Click picture for 1. -3x – 2 > 28 answers 2. X + 6 < 5 4 3. 6x + 10 < 22 4. -2x – 5 < 18 3
  6. 6. 1. X < -10 2. X < -4 3. X<2 4. X > -34.5 Prev next
