Question

combine any like terms in the expression. if there are no like terms, rewrite the expression. 10k + 7j + j - 8j

Explanation:

Step1: Identify like terms (terms with \( j \))

The terms with \( j \) are \( 7j \), \( j \), and \( -8j \).

Step2: Combine the like terms

Combine the coefficients of \( j \): \( 7 + 1 - 8 \). So, \( 7j + j - 8j=(7 + 1 - 8)j = 0j\). The term \( 10k \) has no like terms, so it remains.

Step3: Simplify the expression

Since \( 0j = 0 \), the expression simplifies to \( 10k+0 = 10k \).

Answer:

\( 10k \)
