# How do you identify the terms, like terms, coefficients and constants in each expression: -5x + 4 - x - 1?

The given expression has $4$ terms.

#### Explanation:

$\textcolor{red}{- 5 x} \textcolor{b l u e}{+ 4} \textcolor{red}{- x} \textcolor{b l u e}{+ 1}$

The given expression has $4$ terms.

The like terms are those which have exactly the same variables, there are two types of terms: those in $x$ and the number terms.

$\textcolor{red}{- 5 x \mathmr{and} - x}$ are like terms with the variable $\textcolor{red}{x}$

$\textcolor{b l u e}{4 \mathmr{and} - 1}$ are like terms, also called constants because their value never changes.

The numerical coefficient is the number at the front of the term. It would be better to simplify the expression and then give the coefficient.

$- 5 x + 4 - x - 1 = - 6 x + 3$

The coefficient of $x$ is $- 6$
