Hello Vinay

If the value Of "x" is something, then the value of 3x would be triple of it.

For example:
Let's assume x = 10
Then, 3x = 10 * 3
which implies 3x = 10
You can clearly see that if "x" was 10 then "3x" would be 30 which is just the triple of it.

So whatever the value of x is, the value of 3x would be triple of it.

Hope this answer helps! Thank You!!!
