Not B. there is only one bc.
OpenStudy (texaschic101):
they have to be exactly the same letters...
example :
a + 4a --- like terms
b + ab -- unlike terms
ab + ba -- like terms

Hello?

I am confused. It is none of them
OpenStudy (texaschic101):
3(x - 5) = 8x - 32
3x - 15 = 8x - 32
3x - 8x = -32 + 15
-5x = - 17
x = 17/5 or 3 2/5
