Question

what will be the simplified expression if we combine like terms in $9b + 1 - 4b - 5$?

Explanation:

Step1: Identify like terms

Like terms for \(b\): \(9b\) and \(-4b\); like terms for constants: \(1\) and \(-5\).

Step2: Combine \(b\)-terms

\(9b - 4b=(9 - 4)b = 5b\).

Step3: Combine constant terms

\(1-5 = -4\).

Step4: Form simplified expression

Combine the results: \(5b-4\).

Answer:

\(5b - 4\)
