Simplify

Question

-19c+13y+18c-12y

a
c-y

b
-c+y

c
2c-y

Answer 1

To simplify the expression \(-19c + 13y + 18c - 12y\), we can combine like terms.

1. Combine the \(c\) terms: \(-19c + 18c = -1c\) or \(-c\).

2. Combine the \(y\) terms: \(13y - 12y = 1y\) or \(y\).

Now, putting it all together: \(-c + y\).

This can be rewritten as: \(-c + y = -c + y\).

So the simplified expression is: \(-c + y\).

Now, looking at the provided options:

a. \(c - y\)

b. \(-c + y\)

c. \(2c - y\)

The answer is b: \(-c + y\).
