Question

write an expression that is equivalent to $8a - 5 - 3a - 7$. $8a - 5 - 3a - 7 = \boxed{?}a - \boxed{?}$

Explanation:

Step1: Combine like terms for \(a\)

We have \(8a\) and \(-3a\). Combining them: \(8a - 3a=(8 - 3)a = 5a\)

Step2: Combine constant terms

We have \(-5\) and \(-7\). Combining them: \(-5-7=-12\)
So the equivalent expression is \(5a - 12\)

Answer:

\(5\) \(a - 12\) (First box: \(5\), Second box: \(12\))
