(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A lab has a 20% acid solution and a 50% acid solution. How many liters of each are required to obtain 600 liters of a 30% acid solution?

2. Relevant equations

3. The attempt at a solution

.20x + .50(600 - x) = .30(600)

.20x + 300 - .50x = 180

-0.3x + 300 = 180

- 300 -300

-0.3x = -120

----- -----

-0.3 -0.3

x = 400 liters

I am sure that the answer is wrong. Can anyone tell what im doing wrong, or how to set the problem up properly?

Thank you
