Answer:


\boxed{x<12}

Solution Steps:

______________________________

1.) Subtract 60 from both sides:


  • 60-60= Cancels Out.

  • 240-60=180.

- We subtract on both sides to get rid of the extra numbers, so at the end of the equation we'll be able to get x alone. To do so you have to do the opposite of what you see.

Equation at the end of Step 1:


  • 15x <
    180

2.) Divide both sides by 15:


  • 180 ÷
    15=12

  • 15x ÷
    15=x

- Since 15 is positive, the inequality direction remains the same.

Equation at the end of Step 2:


  • x <
    12
