10x-50%3C100x-80 Start with the given inequality.


10x%3C100x-80%2B50 Add 50 to both sides.


10x-100x%3C-80%2B50 Subtract 100x from both sides.


-90x%3C-80%2B50 Combine like terms on the left side.


-90x%3C-30 Combine like terms on the right side.


x%3E%28-30%29%2F%28-90%29 Divide both sides by -90 to isolate x. note: Remember, the inequality sign flips when we divide both sides by a negative number.


x%3E1%2F3 Reduce.
