Question

Which pairs are like terms in the expression (2/5) y + (1/5) x - 0.2y -6 + (-2)

Answer 1

(2/5)y and -0.2y

-6 and -2

Explanation:

"like terms" means having the exact same variable(s) with the exact same exponent.

constant factors in the term can be different.

remember that x⁰ = 1, and so, pure constants are "like terms" too, as they can be seen as constant factor times variable⁰.
