You can put this solution on YOUR website!
Are you asking for 4 Liters of pure (100%) antifreeze?

Here is a lesson which fits your (this) form:
Two-Part Mixture: One material Quantity Unknown

If you find a result, check the result in your original equation to find if it works or not.

To start,
Let x = volume of water to add.
4%2A100%2F%284%2Bx%29=60, and you would only have trouble for not understanding the equation. If you do understand the equation, then the steps to solving for x should be no trouble.
