Question

The sum of one-third a number and twenty-five is as much as twice the number

Answer 1

The number is 15

Explanation:

1/3(number) + 25 = 2(number)

subtract 1/3(number) from each side

25 = 2(number) - 1/3(number)

25 = 6/3(number) - 1/3(number)

25 = 5/3(number)

multiple each side by 3/5, which is the reciprocal of 5/3

25(3/5) = number

15 = number
