Which expression is equivalent to 5(a−3b)−4a+b?(1 point)Responsesa−14bA minus 14 b−a−2bnegative A minus 2 b9a−b9 A minus b9a−9b

Answer 1

To simplify the expression $5(a-3b)-4a+b$, we'll follow these steps:

1. Distribute the 5 into the parentheses: $$5(a-3b)=5a-15b$$

2. Substitute this back into the expression: $$5a-15b-4a+b$$

3. Combine like terms:

   • For the $a$ terms: $5a-4a=1a$ or simply $a$
   • For the $b$ terms: $-15b+b=-15b+1b=-14b$

Thus, combining these results, we get: $$a-14b$$

The equivalent expression is: $$a-14b$$

So, the answer is $a-14b$.
