You've already given a full, explicit description of ' X ' so there's nothing to solve. The expression (X = 15) sounds like it's the solution to an earlier equation.
There are an infinite number of solutions for the equation x/y = 15. One example is; 60/4=15
If: 11x+25 = 7x+15 then there is only one solution and it is x = -2.5
It is a quadratic equation and its solutions are: x = 3 and x = 5
8 = 15 - 7 8 = 8 Yes it is an equation.
This is called an equation....

15 = 5b
It isn't entirely clear what you mean "for 15 and 10". If you want an equation that has those solutions, you can simply write:(x - 15) (x - 10) = 0 If you wish, you can multiply the polynomials out. The solutions will be the same, but the resulting equation will be harder to solve.

2x - 3 = 57 or 3x + 15 = 105 or many others
8 = 15 - 7 8 = 8 Yes it is an equation.
This is called an equation....
The two numbers are... 12 & 15. The equation is... x equals y times 3
y=±√15
