How many weeks will it take for David and Emily to have the same amount of money?. Equations in two variables. Solving Systems of Equations. Eventually, we will ask: “Under what circumstances can we solve a system of equations in which there are more variables than unknowns for some of the variables in terms of the others?” . Differential Equations. In this class we will focus on solving ordinary differential equations that represent the physical processes we are interested in studying. With perhaps a few exceptions the most complicated differential equation we will look at will be second order, which means it will look something like.
