Spending three minutes solving a system of equations by hand? Don't. On the Digital SAT, enter both equations into the built-in Desmos graphing calculator: 3x minus 2y equals 12, and y equals 2x minus 5. The two lines appear, and their intersection is the ordered pair that solves both. Here, it's negative 2, negative 9-not 2, negative 1. So if the question asks for x plus y, calculate negative 2 plus negative 9: negative 11.
