y + 1.2y + 1.2z

Someone told me that the answer was 2.2y + 1.2z

1. Is that true?

2. How did the 1.2y turn into 2.2y?

You are very welcome. :-)

1y + 1.2y = 2.2y

Yes that answer is correct.

Ohhh! Now I understand! Thank you so much!

To simplify the expression y + 1.2y + 1.2z, we combine like terms.

1. To determine if the answer is 2.2y + 1.2z, we need to simplify the given expression:
y + 1.2y + 1.2z
Combining the y terms, we get:
1y + 1.2y = 2.2y
So, the expression simplifies to:
2.2y + 1.2z

2. The 1.2y turned into 2.2y because when we combine y and 1.2y, we add their coefficients. The coefficient of y is 1, and the coefficient of 1.2y is 1.2. Adding these coefficients together gives us 1 + 1.2 = 2.2. Therefore, the 1.2y term became 2.2y.
