You start of with a number, ( this number can be any number) so think of it as an unknown number. the number shall be denoted as x
so you have x
you want triple the number
3x
you also want to double the number
2x
you want the difference so you subtract these two terms
3x-2x
To solve this, simply multiply:
5 x 7 = 35

Answer:
20/n+10 = 10/n+20 n
multiply both side n,
n (20/n+10) = n(10/n+20 n)
20+10n = 10+20n^2
20+10n -20 = 10+20n^2 -20
10n = 20n^2 -10
10n - 10n = 20n^2 -10 -10n
0 = = 20n^2 -10 -10n
20n^2 -10 -10n = 0
n = 1 or n = -0.5
