Hinzugefügt: 2026-05-17

To solve a system of equations by substitution, isolate one variable in one equation, substitute that expression into the other equation to solve for the remaining variable, then substitute back to find the first variable; for the system x - y = 4 and 2x + y = 11, the solution is x = 5 and y = 1, representing the intersection point (5, 1).
