Given:
• Maggie's equation: ,-7 x (-12) = -84
• Carlos' equation: ,-7 x (-12) = 84
Let's determine who is right.
To determine let's simplify the expressions on the left.
Hence, we have:
![-7*(-12)=--84=84](https://img.qammunity.org/2023/formulas/mathematics/college/2cpikyv5vdnj1w4q2wq3uk7910j0xmlxq4.png)
Therefore, the correct equation is:
![-7*(-12)=84](https://img.qammunity.org/2023/formulas/mathematics/college/b9bkluscgzpcmpprch34g89j2068qrvc9z.png)
Therefore, Carlos is right.
ANSWER:
Carlos
