Question

Without graphing, classify each system as independent, dependent, or inconsistent.?

4x + 8y =12
x + 2y = -3

x = 6
x = -2

2y = 5x +6
-10x + 4y =8

x - 3y=2
4x - 12y = 8

x+ 4y = 12
2x - 8y = 4

4x + 8y = -6
6x + 12y = -9

4y - 2x = 6
8y = 4x -12

y - x = 0
y = -x

2y - x = 4
1/2x - y =2

Answer 1

4x + 8y =12 [inconsistent]
x + 2y = -3

x = 6 [inconsistent]
x = -2

2y = 5x + 6 [inconsistent]
-10x + 4y = 8

x - 3y=2
4x - 12y = 8 [dependent]

x+ 4y = 12 [independent]
2x - 8y = 4

4x + 8y = -6 [dependent]
6x + 12y = -9

4y - 2x = 6 [inconsistent]
8y = 4x -12

y - x = 0 [independent]
y = -x

2y - x = 4
1/2x - y = 2 [inconsistent]
