    well let's look at it (7x)+(- 9)+(- 2x) = (10)+(- 3x)+(5) you know that subtraction is adding a negative, so what is the sum of the like terms on the left side of the equation?

    so 10 and 5 are like terms because they don't have variables. like terms have the same variable, it could be x or nothing at all. x^2 and x are not like terms, but 4x^2 and 8x^2 are, and 3x and 6x are. at the same time 3 and 9 are like terms in an equation
