15x%2B18%3C=4%285x%2B2%29 Start with the given inequality.


15x%2B18%3C=20x%2B8 Distribute.


15x%3C=20x%2B8-18 Subtract 18 from both sides.


15x-20x%3C=8-18 Subtract 20x from both sides.


-5x%3C=8-18 Combine like terms on the left side.


-5x%3C=-10 Combine like terms on the right side.


x%3E=%28-10%29%2F%28-5%29 Divide both sides by -5 to isolate x. note: Remember, the inequality sign flips when we divide both sides by a negative number.


x%3E=2 Reduce.
