Hello there! y < -15
To solve, isolate y. To do this, subtract 30 from both sides of the equation.
y + 30-30 < 15-30
y < -15
This is your final answer. The statement is saying that y must be less than -15 when you add 30 to it for your final answer to be less than 15.
I hope this was helpful and have a great rest of your day! :)
