Question

subtract.
(3k + 7) - (3k + 5)

Explanation:

Step1: Distribute the negative sign

To subtract the two expressions, we first distribute the negative sign to the terms inside the second parentheses. So, \((3k + 7) - (3k + 5)\) becomes \(3k + 7 - 3k - 5\).

Step2: Combine like terms

Now, we combine the like terms. The \(3k\) and \(-3k\) are like terms, and \(7\) and \(-5\) are like terms. Combining \(3k - 3k\) gives \(0\), and combining \(7 - 5\) gives \(2\). So, \(3k - 3k + 7 - 5 = 0 + 2 = 2\).

Answer:

\(2\)
