It is: y = -4x+12
8x + 12 = 4x - 4 8x - 4x = -4 - 12 4x = -16 x = -4
4[x+3]=4x+12 4x+12=4x+12 it's open.
23 + 15x - 4x = 1215x - 4x = 12 -2311x = -11x= -1
6x+4 = x+12+4x-6 6x-x-4x = 12-6-4 x = 2
If: 4x+(-12) = 8 then 4x = 20 and x = 5
It is: y = -4x+12
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
8x + 12 = 4x - 4 8x - 4x = -4 - 12 4x = -16 x = -4
4[x+3]=4x+12 4x+12=4x+12 it's open.
23 + 15x - 4x = 1215x - 4x = 12 -2311x = -11x= -1
4x + 6 = 6x - 12-4x -4x6 = 2x - 12+12 +1218 = 2xx=9
6x+4 = x+12+4x-6 6x-x-4x = 12-6-4 x = 2
-2
19 (7 + 12 = 4x - 3x)
5x+12 = 4x-88 x = -100
y=4x+2
