I think you wrote the first one wrong
but for : 21c + 18c + 31b – 3b
all you have to do is COMBINE LIKE TERMS.
so 21c + 18c are like terms
and 31b – 3b are also like terms
so you get 39c + 28b
the third one:
Distribute .2
.2(.08 + 7y) + .36y
(.2 x .08) + (.2 x 7y) + .36y
(.016) + (1.4y) + .36y
again combine the 1.4y and the .36y [like terms]
and you get
1.76y + .016
^^
(1.4y + .36y) [thats how you get 1.76=]
