The maximum weight on a roller coaster is 400 pounds (Max = 400).
If your friend weighs 120 pounds (y = 120), what is the most you can weigh so you can ride together (x + y < 400).
x + 120 <_ 400.
y = 120
Subtract 120 from both sides.
x <_ 280.
You can weigh at most 280 pounds (x <_ 280).
I hope this helps!
