Solve each system of equations
31. 4x + 2y = 7
y = 5x
32. t = 2r + 3
5r - 4t = 6
33. y = 2x - 1
3x - y = -1
Graph each system of equations
34. y _< 2x + 2
y < - x + 1
35. 2x + y < 1
y > - 2x + 3
Graph each system. Find all vertices. Find the value for the obj. function
36. 3x + y _< 7
x + 2y _< 9
x _> 0, y _> 0
Maximum for P = 2x + y
37. x + y _< 11
2y _> x
x _> 0, y _> 0
Minimum for P = 3x + 2y
Solve each system of equations
38. x - y + Ƶ = 1
x + y + 3Ƶ = -3
2x - y + 2Ƶ = 0
39. 3x = 3y = 6Ƶ = 9
2x + y + 3Ƶ = 7
x + 2y - Ƶ = -10
40. x - y + 2Ƶ = -7
y + Ƶ = 1
x = 2y + 3Ƶ
