6x+4 = x+12+4x-6 6x-x-4x = 12-6-4 x = 2
-2x + 6 <= 4x + 18 -2x <= 4x + 12 -12 <= 6x -2 <= x
-4x+3 = 23+6x -4x-6x = 23-3 -10x = 20 x = -2
4x - 8 = 12 + 6x 4x - 6x = 12 + 8 -2x = 20 -x = 20/2 x = -10 Check: 4(-10) - 8 = 12 + 6(-10) -40 - 8 = 12 + -60 -48 = -48
10x-7=4x+5 +7 +7 10x=4x+12 -4x -4x 6x=12 /6 /6 x=2
6x+4 = x+12+4x-6 6x-x-4x = 12-6-4 x = 2
Add 12 to each side: 4x + 6x = 20 ie 10x = 20 so x = 2
-2x + 6 <= 4x + 18 -2x <= 4x + 12 -12 <= 6x -2 <= x
6x^2 +32x +12 -4x -3x^2 -36 = 3x^2 +28x -24 simplified
-4x+3 = 23+6x -4x-6x = 23-3 -10x = 20 x = -2
2(x^2 + 2)(x + 3)
2(x^2 + 2)(x + 3)
4x - 8 = 12 + 6x 4x - 6x = 12 + 8 -2x = 20 -x = 20/2 x = -10 Check: 4(-10) - 8 = 12 + 6(-10) -40 - 8 = 12 + -60 -48 = -48
10x-7=4x+5 +7 +7 10x=4x+12 -4x -4x 6x=12 /6 /6 x=2
this is the same as 6x - 2 = 6x - 2! There are an infinite number of possibilities for "x".
Yes there is say that the question is 4x+12=6x you need to subtract the 4x to get 12=6x then divide the 6x by 6 and do the same with the 12 to get an answer of 2
- 4X - 6X + 2 = 2(- 2X - 3X + 1) -------------------------that is all the factoring I can see to do here
