Step-by-step explanation:

Terms are the contents in the equation of such. For example, 10+4n. There are two terms. Like terms, are when the terms have the same variable. For example, 4m and 8m. Coefficients are the number next to a variable. For example, 9x. 9 is the coefficient. Constants are numbers without a variable. Numbers like 7, 8, 9, 10-- they don't have variables so they are constants in an equation. Now, knowing this information lets get to work!
