Which equation can be used to represent "six added to twice the sum of a number and four is equal to one-half of the difference of three and the number"?
O6 + 2(x + 4)=1/2(3-x)
O 6+ 2(x + 4) =1/2(x-3)
O (6 + 2)(x + 4) = 1/2(3 - x)
O (6 + 2)(x + 4) = 1/2(x-3)

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.
