<p>i always get confused when CB uses terms like divisible by, divided by,
and now this one:
a number is added to 9 less than twice the number. if the result is 180, what is the number?
x+9-2x=180 or 2x-x+9=180</p>
<p>edit: thru trial and error, 2x-x+9=180 seems to be the correct .
so in this case, 5 less than x , is x-5? yeah??</p>
