Answer:
The answer is 35
Step-by-step explanation:
Let the number of files he had be x
He gave 3/5 of the files
That's
3/5x
After that he still had 14 files left which means when we subtract 14 from the original files we should get 3/5 of the original files
So we subtract 14 from the original number of files
That's
x - 14
We equate the two statements
that's
[tex] \frac{3}{5} x = x - 14[/tex]
Multiply through by 5
[tex]5 \times \frac{3}{5} x = 5x - 70[/tex]
We have
3x = 5x - 70
3x - 5x = 70
-2x = - 70
Divide both sides by -2
We have the final answer as
x = 35
Therefore he had 35 files at first
Hope this helps you
