The answer to this question is x<6
15x + 12y = 489
But we need another statement to create second equation
2.)
-->
So y = -4.
3.)
Combine like terms:
-->
Isolate x --->
---->
So x = -2
4.)
-->
Combine like terms --->
This equation has many possible solutions.
5.)
-->
Combine like terms --->
---->
----->
So x = -1.
6.)
Distribute --->
This equation has many possible solutions.
