联立方程
Simultaneous Equations
理解两个线性方程可以通过求它们图像的交点来联立求解，并从图形和代数角度解释为同时满足两个方程的一对数值。
Understand that two linear equations can be solved simultaneously by finding the point where their graphs intersect, and interpret this graphically and algebraically as the pair of values satisfying both equations

{{name}}能否解释，联立求解两个方程意味着找到同时满足两个方程的那对值，并展示这在图像上是什么样子？
Can {{name}} explain that solving two equations simultaneously means finding the one pair of values that satisfies both at once — and show what that looks like on a graph?
