# Solutions to Systems of Linear Equations

Determine if the given ordered pair is a solution to the system:

12. 2x + y = 5 (4, -3)

x - y = 1

22. 4x - y = -2 (-1, -2)

3x + y = -5

Solve each system of equations by the graphing method:

32. x - y = 4

x + y = 2

48. -4x + 4y = 4

y = x + 1

Solve each system of equations by the substitution method:

52. 8x + 3y = -14

-x + 2y = -3

66. -3x + 2y = 8

y = 3/2x + 3

Solve each system of equations by the addition method:

74. 3x + 5y = 4

-4x + 2y = -1

88. 6x + 2y = 8

2x - y = 6
