-------------
Neither of those are equations.
Equations have equal signs.

If they were, they wouldn't change in months or years.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

As you formulated it in your post, it sounds good for the day of April, 1.

Below is how it should be formulated: 

     At which value of "x" the expressions 15x + 50 and 20x + 10 are equal ?

To answer this question, make an equation

15x + 50 = 20x + 10.

and then simplify and solve it:

50 - 10 = 20x - 15x ---> 40 = 5x ---> x = 8.

Answer. x= 8: eight months (? if x is month . . . )
