4x + 3 cannot equal 4x + 12:4x + 3 = 4x + 12 (given)3 = 12 (subtract 4x from both sides)
8x + 12 = 4x - 4 8x - 4x = -4 - 12 4x = -16 x = -4
4x+6=6x-12
if 4x+1=12 4x+1-1=12-1 4x=11 4x/4=11/4 x=11/4
At the x-intercept, y=0 so...2y - 4x = -122(0) - 4x = -12-4x = -124x = 12x = 12/4x = 3
2(4x + 4) = (4x - 12) 8x + 8 = 4x - 12 8x - 4x + 8 = 4x - 4x - 12 4x + 8 = -12 4x + 8 - 8 = -12 - 8 4x = -20 4x/4 = -20/4 x = -5
8
8-3x-x = 12 8-4x = 12 -4x = 12-8 -4x = 4 x = -1
4x + 3 cannot equal 4x + 12:4x + 3 = 4x + 12 (given)3 = 12 (subtract 4x from both sides)
8x + 12 = 4x - 4 8x - 4x = -4 - 12 4x = -16 x = -4
4x+6=6x-12
If: 4x+(-12) = 8 then 4x = 20 and x = 5
4x + 6 = 6x - 12-4x -4x6 = 2x - 12+12 +1218 = 2xx=9
(4x2 - 13x - 12)/(4x+ 3) = (4x + 3)(x - 4)/(4x + 3) = (4x + 3)(x - 4)/(4x + 3) = x - 4 :)
