- Mixture Problems - Algebra - Socratic2x + 7y=200. This is equation (1) Setting up the second equation, Sum of amounts of each acid = Amount of mixture. x+y=40. To make at least one term of this equation identical to a term of equation (1), we'll multiply the entire equation by 2, 2x+2y=80. This is equation (2)
