This poster shows the luggage allowance for passengers with Economy class air tickets.
To avoid paying for additional charges, your luggage should not exceed 30 kg.
Let us use the letter w to represent the mass of the luggage in kilograms.
We say w is to be less than or equal to 30

Notice w is on the left side (lesser) and 30 is on the right side.
Note w can be allowed to be equal to 30.
