Answer:

12c - 9d + 3

Step-by-step explanation:

(9 c − 8 d ) + ( 2 c − 6 ) + ( − d + 3 )

Combine like terms ( the d's with the d's, the c's with the c's and the numbers without the variables with the number w.out the variables)

9c - 8d + 3c - 6 - d + 3

12c - 9d + 3

That is at it's simplest form
