Question 447214: how many liters of 45% acid solution must be mixed with 10 liters of 65% acid solution to get 45% acid solution Answer by rwm(914) (Show Source):
You can put this solution on YOUR website! Can't be done.
I suspect you copied the problem incorrectly
You can't add 45% solution to a 65% percent solution and still come out with 45%
You can get close but never reach it.
.45x+10*.65=.45(x+10)
