## 2.5. Set of Linear Equations in Two Variables

Two linear equations in x and y can be interpreted as two straight lines. The algebraic solution is the intersection point of these two lines. Just type the following lines into the input field and press the Enter key after each line.

g: 3x + 4y = 12

h: y = 2x - 8

S = Intersect[g, h]

To change the equations you can right click (MacOS: Apple + click) one of them and select Redefine. Using the mouse you can drag the lines in Move or rotate them about a point using Rotate around point.
