The required numbers are 18,46 and 23.
This problem requires the idea of linear equation of 1 variable.
To clear up the linear equation we also need to recognize the BODMAS policies and the way to solve algebraic equations.
in this query the sum of the 3 numbers is 87.
let us count on that the third variable be x.
the second one variable is 2x.
The first variable is (x-5).
Now according to the question,
![(x-5)+2x+x=87](https://tex.z-dn.net/?f=%28x-5%29%2B2x%2Bx%3D87)
⇒ ![4x-5=87](https://tex.z-dn.net/?f=4x-5%3D87)
⇒ ![4x=87+5](https://tex.z-dn.net/?f=4x%3D87%2B5)
⇒![4x=92](https://tex.z-dn.net/?f=4x%3D92)
⇒ ![x=\frac{92}{4}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B92%7D%7B4%7D)
∴ x=23
So, the third number is 23.
The second number is 2x i.e., 46.
The first number is (x-5) i.e., 18.
