<PRE><B>Question 985740</B>
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 - {{{2/3}}}n = 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 - {{{2/3}}}(6) = 3(6)
22 - 4 = 18
