A scientist needs 60 liters of a 60% acid solution. He currently has a 40% solution and a 70% solution. How many liters of each does he need to make the needed 60 liters of 60% acid solution?
----------------
Equation:
acid + acid = acid
----------------------
0.40x + 0.70(60-x) = 0.60*60
-----
40x + 70*60 - 70x = 60*60
-----
-30x = -10*60
x = 20 liters
----
Gabe needs 20 liters of the 40% solution.
He also needs 40 liters of the 70% solution.
X + 6 = 33
x = 27
hope this helps :D
8 is 3+5, that would be the correct answer
