-2x + 5
-8x - 10 - 20 = -8x - 30
7y+ 8x + 4= 20 + 8x- 8x - 8x7y + 4 = 20- 4 - 47y=16/7 /7y= 2.28the /7 means divide by 7 :)
8x + 20 = 4 (2x + 5)
8x -12 ... 4(2x -3)
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)
It is: 8x-20
11x + 8 = 8x + 20 3x + 8 = 20 3x = 12 x = 4
4
-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
-24
6x-20 = 8x 6x-8x = 20 -2x = 20 x = -10
If you mean: 8x-2y = -20 then y = 4x+10 whereas 4 is the slope and 10 is the y intercept
