Identify the constants in the expression below.

5x - 3y + 2x - 15 + 2y + 9

First of all a constant is a non-variable which would obviously be a number so in this equation the constants are: 5,3,2,15,2, and 9

The constants are - 15 and 9

Step-by-step explanation:

Constants are those numerical values that will never change, despite the value of x. The easiest way to find them are by finding those numbers that are not affecting x in any way.
