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.
