Question

which expression is equivalent to $8a + 3 - 4a + 5$?
answer
$12a$ $8 + 4a$
$12a - 2$ $12$

Explanation:

Step1: Combine like terms for \(a\)

We have \(8a - 4a\). Combining these, we get \( (8 - 4)a = 4a \).

Step2: Combine constant terms

We have \(3 + 5\). Combining these, we get \( 8 \).

Step3: Combine the results

Putting the results from Step1 and Step2 together, we get \(4a + 8\) (which is the same as \(8 + 4a\)).

Answer:

\(8 + 4a\) (corresponding to the option "8 + 4a")
