Solve algebraically the simultaneous equation
WebOct 31, 2024 · A system of equations is when two or more variables are related, and equations are built to find the values of each variable. In this problem, the equations are: x² + y² = 25. y = 2x - 2. Replacing the second equation in the first: x² + (2x - 2)² = 25. x² + 4x² - 8x + 4 = 25. 5x² - 8x - 21 = 0. Which is a quadratic equation with ... WebSpecification notes. A19. Solve two simultaneous equations in two variables (linear / linear or linear/quadratic) algebraically.
