Answer :
-2x - 4y = 1
12y = -6x - 3
12 12
y = -0.5x - 0.25
-2x - 4(-0.5x - 0.25) = 1
-2x + 2x + 1 = 1
0x + 1 = 1
- 1 - 1
0x = 0
0 0
x = 0
-2(0) - 4y = 1
0 - 4y = 1
-4y = 1
-4 -4
y = -0.25
(x, y) = (0,-0.25)
12y = -6x - 3
12 12
y = -0.5x - 0.25
-2x - 4(-0.5x - 0.25) = 1
-2x + 2x + 1 = 1
0x + 1 = 1
- 1 - 1
0x = 0
0 0
x = 0
-2(0) - 4y = 1
0 - 4y = 1
-4y = 1
-4 -4
y = -0.25
(x, y) = (0,-0.25)
