Helloo!!

let the number be x (3x-2)/(2x+5) = 13/15. 
13(2x+5) = 15(3x-2)

26Nlx + 65 = 45x - 30,
N = 5.
hope it helps

Let the number be x.

Given, Subtracting 2 from thrice a number = 3x-2.

Given, the sum of twice the same number and 5 = 2x + 5.

Given, 3x-2/2x+5 = 13/15

            13(2x+5) = 15(3x-2)

           26 + 65 = 45x - 30

           19x = 95

               x = 5.


The number is 5.
