solving the equation is so much easier than having to build it by a word problem :(

A scientist needs 10 liters of a 20% acid solution for experiment, she only has a 5% solution and a 40% solution. To the nearest 10th of the liter, about how many liters of the 5% and the 40% solutions should she mix to get the solution she needs? write the equation.
