Respuesta :
7d-6 because adding both negatives together gives you -6, and the -d gets subtracted from 8d
Hi :)
The way we'll simplify this is we'll combine the like terms, which are the d's and the constant terms:
8d-4-d-2
A great way is to write the d's together and the constant terms together:
8d-d-4-2
Now combine:
7d-6
