Uhh, assuming X > 0, then 3X?

You should be familiar with using variables to represent quantities - if you are not, you really should reread your textbook first.

Hi,

one number is three times as large as another smaller number X.

⇒ the Larger number is 3X

It is common to express one number in terms of another.

For Ex

one number is 5 more than another number X

⇒ Larger number is X + 5

As it goes... problem may read:

one number is 5 more than another number X and their sum is 15

X + X + 5 = 15    Combining Like Terms (subtracting 5 from both sides of = sign)

 2X = 10    (Dividing both sides by 2)

  X = 5, the smaller number.  The larger number is 10

Wish You the Best in your Studies.
