Two thirds of a number is subtracted from 22 and the answer is three times the number.
Write an equation and solve
:
just write the equation for what it says
22 - 2%2F3n = 3n
multiply equation by 3 to get rid of the denominator, you then have
3(22) - 2n = 3(3n)
66 - 2n = 9n
66 = 9n + 2n
66 = 11n
n = 66/11
n = 6

Check this
22 - 2%2F3(6) = 3(6)
22 - 4 = 18
