Question 1038298
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+9x=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*28}}}, which equals 252.
Check your answer!
{{{28+9*28=280}}}?
