Responses

9a−b
9 A minus b

−a−2b
negative A minus 2 b

9a−9b
9 A minus 9 b

a−14b
A minus 14 b

Answer 1

To simplify the expression \( 5(a - 3b) - 4a + b \), we'll follow the steps of distributing and combining like terms.

1. Distribute \(5\) into the parentheses:

   \[ 5(a - 3b) = 5a - 15b \]

2. Substitute this back into the expression:

   \[ 5a - 15b - 4a + b \]

3. Now, combine like terms:

   • For the \(a\) terms: \(5a - 4a = 1a \) (or just \(a\))
   • For the \(b\) terms: \(-15b + b = -14b\)

4. Putting it all together:

   \[ a - 14b \]

Thus, the simplified expression that is equivalent to \( 5(a−3b)−4a+b \) is:

\[ \boxed{a - 14b} \]

The correct response is:

a−14b (A minus 14 b)
