Question

subtract.
(7u + 4) - (7u + 2)

Explanation:

Step1: Remove parentheses

To subtract the two expressions, we first remove the parentheses. Remember that the negative sign in front of the second parentheses affects both terms inside it. So we have:
\(7u + 4 - 7u - 2\)

Step2: Combine like terms

Now we combine the like terms. The \(7u\) and \(-7u\) are like terms, and \(4\) and \(-2\) are like terms.
For the \(u\)-terms: \(7u - 7u = 0\)
For the constant terms: \(4 - 2 = 2\)

Answer:

\(2\)
