5x+12 = 4x-88 x = -100
3x-4x=12 that means -x equals 12 so x equals -12
-2x=-4x*24 x=12
4x-5=7 4x=12 x=3
8x + 12 = 4x - 4 8x - 4x = -4 - 12 4x = -16 x = -4
If: 4x-4 = 12 Then: x = 4
8-3x-x = 12 8-4x = 12 -4x = 12-8 -4x = 4 x = -1
If: 4x+(-12) = 8 then 4x = 20 and x = 5
If: 4x-4 = 12 Then: x = 4
5x+12 = 4x-88 x = -100
3x-4x=12 that means -x equals 12 so x equals -12
-2x=-4x*24 x=12
4x-5=7 4x=12 x=3
The x-intercept is found when "y" has no value 4x-3(0)=12 4x=12 x=3 x-int. = 3
8x + 12 = 4x - 4 8x - 4x = -4 - 12 4x = -16 x = -4
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
X = -12 I hope.
