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.
