2 System of Equations Solver (Interactive)

① This example demonstrates an interactive solver for a system of two linear equations, allowing users to modify the equations via input fields and observe the intersection point in real time. ② The core mathematical concept is the geometric interpretation of linear systems—the solution corresponds to the intersection of two lines, involving slope, intercept, and standard line equations. ③ Construction highlights: Textfield commands create two input boxes (inputBox1, inputBox2) for user-entered equations; Intersect computes the intersection point A; Slope obtains the slopes (m, m_1); displayed elements include equation text (FormulaText) and coordinates (xofred, yofred, xofblue, yofblue). ④ Suitable for middle school to high school students learning algebra and coordinate geometry, as well as for classroom demonstrations by teachers.
