3x-15%3C9%2B7x Start with the given inequality



3x%3C9%2B7x%2B15Add 15 to both sides


3x-7x%3C9%2B15 Subtract 7x from both sides


-4x%3C9%2B15 Combine like terms on the left side


-4x%3C24 Combine like terms on the right side


x%3E%2824%29%2F%28-4%29 Divide both sides by -4 to isolate x (note: Remember, dividing both sides by a negative number flips the inequality sign)



x%3E-6 Divide

Answer:
So our answer is x%3E-6
