Answer 6

This is a simple problem, but i guess its trying to illustrate something...
okay first it states a fact, 21<30, which u know is true.

Then it goes on to add 15 to each side.
Since u know 21<30 , by adding 15 to each side. the inequality sign will still stay the same.
This means irregardless of wat value you add to both side, the rule still stands.

For any value of x,
21 +x < 30+x. This statement is always true.
