Question 156788
If you make your number x then you can create an equation that looks like {{{(1/2)x+3=(2/3)x}}}. Then solve the equation for x.
Subtract {{{(1/2)x}}} from both sides => {{{3=(1/6)x}}} (Know your fractions!)
Multiply both sides by 6 => {{{18=x}}}
To check the answer: half of 18 is 9 and two-thirds of 18 is 12 and 9 is three less than 12
