Question

Combine like terms in the following expression 9x+ x

Answer 1

10x

Explanation:

9x + x is the same as 9x + 1x, so adding the two together would make 10x, because they are like terms (have the same variables and exponents).

Answer 2

For this case we must combine similar terms.

It is observed that the expression
`9x + x` is composed of two terms, in addition each term is of degree 1, they only have a different coefficient.

Since both have the same degree, the coefficients can be added. We take into account that equal signs are added and the same sign is placed:

`9x + x = (9 + 1) x = 10x`

ANswer:

`10x`
