Answer: x = -39
Step-by-step explanation:
85= -6x+7+4x combine like terms (-6x, 4x)
85= -2x+7 subtract 7 from both sides
78= -2x divide both sides by -2
x= -39
Judging by the question I noticed that the two both share x^3 in common. You can divide x^4 by x^3 and get x as a result, and x^3 can still divide into itself.
Thus your answer should be C, x^3
