1. In order to solve the below “System of Inequalities”
______________________________________________________________
2. We use the “cover method”
______________________________________________________________
3. [Equation #1] Covering the “3x” gives us y =6, covering
______________________________________________________________
the 2y gives us x = 4.
______________________________________________________________
[Equation #2] Covering the “3x” gives us – y = 3, therefore
______________________________________________________________
y = – 3. Covering the – y gives us 3x = 3, where x = 1.
______________________________________________________________
4. Plotting each point, graphing and shading each line gives
______________________________________________________________
us the area of intersection, the solution.
