Answer 1

c

BECAUSE I SAID SO HUH YOU GOTTA PROBLEMO??

Answer 2

C. 4(x-3)-x

Explanation:

All of the given expressions are equivalent to 3x+12 except selection C. Using that in your equation makes it be ...

... 3(x +1) +9 = 4(x -3) -x

... 3x +12 = 3x -12

... 12 = -12 . . . . . false

There is no value of x that will make this true, hence NO SOLUTION.

Comment on the other choices

3x+12 = 3x+12 has an infinite number of solutions, as any value of x will make this true.
