2a+3b+4c cannot be added. They are not like terms. Like terms need to have the same variable in order to be added.
It cannot be simplified any further so it is: 3a + 24b + 4c
5P + 111 + 136 + 20 = 4c + 4 5P + 267 = 4c + 4 -4 -4 5P + 263 = 4c You cannot cimplify it anymore, unless by 'c' you meant 'P'. 5P + 263 = 4P -5P -5P 263(-1) = -P(-1) -263 = P
4C times D is the same as 4CD in algebra which means 4*D*C
3x
Without further information, all we can do is simplify: 4c + 4d = 4(c + d)
4c2 + 5c + 2c = 4c2 + 7c = c(4c + 7)
4c
6c-18=4c Why can rearrange this and simplify to 2c=18, which means that c = 9
4c+2 = 3c+9 4c-3c = 9-2 c = 7
9
c2 + 4c + 4 =(c + 2) (c + 2)= (c + 2)2
6c-4c =2c
b+b+b+c+c+c+c =3b+4c
(c + 2)(c + 2) or (c + 2)2
17-3= 4c+3c c=2
b + b + b + c + c + c + c = 3b + 4c
