Answer:
Step-by-step explanation:
<u>Let's check his work by simplifying the given expression.</u>
- 2(x - 2) - 2(3)
- => 2x - 4 - 6
- => 2x - 10
When I compare Marty's result and this result, they are un-equal. Hence, Marty is incorrect.
<u>Marty's mistake</u>
- Marty must've got the problem wrong because of not understanding the distributive property.
- He probably forgot to multiply -2 by 2. Instead, he only subtracted 2 when he should've subtracted 4 from 2x.
