Question

If 3ax+b=c then x equals
A) c+b-3a

B) c-b
over
3a

C) c-b+3a

D) b-c
over
3a

Which is the best answer??

Answer 1

c-b/ 3a 1st, subtract b from both sides, then divide both sides by 3a, the side with X cancels out and leaves you with c-b/3a

Answer 2

$3ax+b=c\\ 3ax=c-b\\ x=\dfrac{c-b}{3a}$
