6x-9=39 so 6x=48 and 8x6=48 so x=8
4x+8
-x2 + 6x + 16 = -(x2 - 6x - 16) = -(x - 8)(x + 2) = -(8 - x)(x + 2)
6x+4=3x+12 => 6x-3x=12-4 => 3x=8 => x=8/3=2.666...
8+6x = ? 8+6*5 = ? 8+30 = ?
6x-9=39 so 6x=48 and 8x6=48 so x=8
x=-8
x2 + 6x + 8 = (x + 4)(x + 2)
6x + 8 = 13, 6x = 13 - 8, 6x = 5, x = 5/6
4x+8
-x2 + 6x + 16 = -(x2 - 6x - 16) = -(x - 8)(x + 2) = -(8 - x)(x + 2)
x2 + 6x + 8 =(x + 2)(x +4)
6x+4=3x+12 => 6x-3x=12-4 => 3x=8 => x=8/3=2.666...
9x + 8 = 6x + 20(- 8 from both sides)9x = 6x + 12(- 6x from both sides)3x = 12(divide both sides by 3)x = 4
6x+4=52 6x=48 x=8
8+6x = ? 8+6*5 = ? 8+30 = ?
6x = 32 - 4y and 4y - 8 = 6x so 32 - 4y = 4y - 8 ie 40 = 8y so y = 5 and x = 2
