Solutions to Systems of Linear Equations
Not what you're looking for?
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
