Question

combine any like terms in the expression. if there are no like terms, rewrite the expression. 4r + 1 - r - 3r

Explanation:

Step1: Identify like terms

The like terms with \( r \) are \( 4r \), \( -r \), and \( -3r \), and the constant term is \( 1 \).

Step2: Combine like terms with \( r \)

\( 4r - r - 3r=(4 - 1 - 3)r \)
\( (4 - 1 - 3)r = 0r \)

Step3: Combine with the constant term

\( 0r+1 = 1 \)

Answer:

\( 1 \)
