Anumber is 40% more than another number. if the sum of the two numbers is 84, find the two numbers

If a number is 40% more than another number, we can say that the new number is equivalent to the sum of the old number and 40% of the old number. Let's try to represent this as an equation. First, let's convert the percentage to a fraction:

Defining as the new number and as the old number, we can say:

Also, we can say:

To solve, let's substitute the first equation into the second equation for and simplify.

We now have found the old number. Using the second equation we found near the beginning, let's find .

The numbers are 35 and 49.
