Question: 3 1/3 is the same as the sum of -1/2 times a number and -3
You can eliminate answer 2 and 4 because they have a plus sign instead of an equals sign. This is because when a problem says "is the same as" it means there should be an equals sign. That leaves you with 1 and 3. In order to solve from here, simply examine the order in which the numbers are listed in the problem. On number 3, it says -1/2 + (-3x) This is incorrect because in the question it said that -1/2 was multiplied by "a number" This means -1/2 is multiplied by x. On number 3, -3 is multiplied by x, so it cannot be correct. This leaves you with answer one as the only remaining option.
