Solve Simultaneous Equations on Casio Calculator (fx-ES Plus EQN Mode)

Learn the fastest way to solve a system of two linear equations with two unknowns using the Equation Mode (EQN) on your Casio fx-ES Plus series calculator (including models like the fx-991ES Plus, fx-300ES Plus, etc.). We solve the system: 3x + 5y = 23 and 2x - y = 11, and show you exactly where to input the coefficients (a, b, and c). This is a massive time-saver for algebra and math classes!
