The Algebra question reads as follows:For her chemistry experiment, Marisol needs 2 liters of a 50% alcohol solution. The lab has two containers,one with 40% alcohol solution and the other with 80% alcohol solution.1. Write a system of linear equations that you can use to determine how many liters of each type of alcoholsolution Marisol should combine to get 2 liters of a 50% alcohol solution. Be sure to define your variables.Ok, let's break down the question into two parts.First, Ms. Marisol needs 2 liters of solutions that equal 50%. In this case, I am going to write out 50% as .5Second, you have 2 containers; one holding 40% alcohol solution (.4) and one holding 80% alcohol solution(.8).Let's label your first container X and your second container Y.The first linear equation will be set up as follows:x+y=2Combining the liquid from X and the liquid from Y equals 2 lit
