Six times a larger number is equal to the sum of a smaller number and 18. The difference of twice the larger number and the smaller number is 6. Let x represent the smaller number and y represent the larger number. Which equations represent the situation? y = 6 x + 18. y = 2 x minus 6. y = 6 (x + 18). Y = 2 (x minus 6). y = one-sixth x + 3. y = one-half x + 6. y = one-sixth x + 3. y = one-half x + 3.
