If: y = 8x+7 then the y intercept is 7 and the slope is 8
-8x+7 = -7x-2 -8x = -7x-2-7 -8x=-7x-9 -8x+7x=-9 -1x=-9 x=-9/-1 x=9
x=-3

X=6

4x+7-8x=17-4x+7=17-4x=10x = -5/2
0. 7 - 3x = 5x + 13 1. 7 - 8x = 13 2. -8x = 5 3. x = -5/8.
-8x -7 = 3x - 13 Add 8x to both sides: -7 = 11x - 13 Add 13 to both sides: 6 = 11x Divide both sides by 11: x = 6/11
7-8x = 21 -8x = 21-7 -8x = 14 x = -1.75
3x - 7 = 5x + 133x - 5x = 13 + 7-2x = 20x = -10x=-3
8x=7x-7 x=-7
Subtract: 2x = -20Divide by 2: x = -10
7 - 8x = 17 7 - 8x - 7 = 17 - 7 -8x = 10 -8x/-8 = 10/-8 x = -10/8 = - 5/4
(2x + 1)(4x - 7)
If: -9-4x = 7-8x Then: x = 4
8x+7=55 8x=55-7 8x=48 x=48/8 x=6
