What value of X makes this equation true? 10×-6=3[×+1/2]

A=14/15
B=13/14
C=15/14
D=14/13​

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.

The answer is 225 miles per 4.5 hours. hope this ; )
