Answer: B

Explanation:

First you must get the X term on its own. To do that, you must remove the +5 because it is on the same side of the > symbol as the x term. When removing a term we must to the opposite to what the equation states so, as the equation say +5 we must -5 from BOTH sides of the > sign instead. This leaves is with -2x>12. To find the value of X, we divide both sides by -2 (since currently the x is multiplied by -2 and we need to do the opposite) and we get x<-6. Remember when dividing by a negative number we flip the sign. The value of x must be lower than -6 and the only value lower than -6 from the given solutions is -4, so the answer is B.
