8x + 12 = 4x - 4 8x - 4x = -4 - 12 4x = -16 x = -4
-1
because 4+4+4=12
x=4, y=9 (4,9)
If you notice, 8x + 4 = 4(2x + 1), but there is an odd coefficient for x2, so there is guaranteed to be some remainder (that is 8x + 4 is not a factor of the polynomial): (24x3 - 5x2 - 48x - 8) ÷ (8x + 4) = 3x2 - 2x - 5 - (x2 - 12)/(8x + 4)
8x + 12 = 4x - 4 8x - 4x = -4 - 12 4x = -16 x = -4
(0,-4)
It equals 8x+12
x² + 8x - 48 = (x + 12)(x - 4) x² + 8x + 48 = (4+(√32)i)(4-(√32)i)
-8x+3y=12 3y = 8x+12 y = (8/3)x + 4 So it will be a line with slope 8/3 and y intercept of 4

4(2x-3)+7=8x8x-12+7=8x-8x..........-8x-12+7=0+12.....+127=12-7...-7No Solution:0≠54(2x-3+7)=8x8x-12+28=8x-8x............8x-12+28=0+12.......+1228=12-28...-28No Solution: 0≠-16
-8x+4=-4xChange -8x into a positive number, so that it cancels itself out..Then add it to -4x.So your problem should look like this:4=4x4 divided by 4 = 1So X=1
The value of x is 2
-1
It's 4. 12 divided by 4 equals 3 40 divided by 4 equals 10
x = -8, y = 10
