6c-4c =2c
4c2 + 5c + 2c = 4c2 + 7c = c(4c + 7)
6c-18=4c Why can rearrange this and simplify to 2c=18, which means that c = 9
4c+1-5+2c = 6c-4.
8c + 5 = 4c - 11Subtract 4c from each side:4c + 5 = -11Subtract 5 from each side:4c = -16Divide each side by 4:c = -4
4 cc
Without further information, all we can do is simplify: 4c + 4d = 4(c + d)
9
6c-4c =2c
4c2 + 5c + 2c = 4c2 + 7c = c(4c + 7)
2a+3b+4c cannot be added. They are not like terms. Like terms need to have the same variable in order to be added.
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
4c+1-5+2c = 6c-4.
It cannot be simplified any further so it is: 3a + 24b + 4c
