Simplify the expression. 4a + 2 - 3c + 6 + 7c - 3 - 3b + 2a -5b

4a+2-3c+6+7c-3-3b+2a-5b you can combine 4a and 2a to get 6a
6a+2-3c+6+7c-3-3b-5b you can combine 5b and 3b to get -8b
6a+2-3c+6+7c-3-8b you can combine 3 and 2 and 6 to get 5
6a+5-3c+7c-8b you can combine 3c and 7c to get 4c
6a+5+4c-8b

4a+2-3c+6+7c-3-3b+2a-5b
= (4a+2a)+ (-3b-5b)+ (-3c+7c)+ (2+6-3) (combine like terms)
= 6a -8b+ 4c+ 5

The final answer is 6a -8b+ 4c+ 5~

Iknow one of the answers is a and maybe b but not 100% sure about b
