Let us represent the first of the unknown numbers with x.
We know that the second of the unknown numbers is 9 times larger than the first, so let us represent it as 9x.
We have been told that these two numbers added together are equal to 280, so...
x%2B9x=280
Add...
10x=280
Now divide both sides by 10...
x=28
So the first of the numbers is 28, and the second is 9%2A28, which equals 252.
Check your answer!
28%2B9%2A28=280?
