Question

simplify the algebraic expression:

(a + 8a - b)

Explanation:

⚡ Using what you learned: simplifying expressions

Step 1: Identify like terms

Group the terms with the same variables together.

$$ (a + 8a) - b $$

Step 2: Combine the coefficients

Add the coefficients of the \( a \) terms. Remember that \( a \) is the same as \( 1a \).

$$ 1a + 8a = 9a $$

Step 3: Write the simplified expression

Combine the simplified \( a \) terms with the remaining \( b \) term.

$$ 9a - b $$

Answer:

$$ 9a - b $$
