7+(-2)

Answer 9

5

Answer 10

right, now what are the like terms on the right side of the equation.

Answer 11

nothing just the 3x right

Answer 12

well a like term does not have to contain a variable

Answer 13

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

Answer 14

oh ok
