2x-4=6x+8
-8= -8
2x-12= 6x
-2x= -2x
-12= 4x
/4=/4
-3=x
6x + 8 = 13, 6x = 13 - 8, 6x = 5, x = 5/6
(4, 8)
x=7
x2 + 6x + 8 = 0 Solve for x.X = -2 or X = -4
9x + 8 = 6x + 20(- 8 from both sides)9x = 6x + 12(- 6x from both sides)3x = 12(divide both sides by 3)x = 4
The quadratic expression x2+6x+8 when factorised equals (x+2)(x+4)
6x + 8 = 13, 6x = 13 - 8, 6x = 5, x = 5/6
y=6x-16 y=-2x+8
It is 8
6x+4=52 6x=48 x=8
X equals to 8
6x = 32 - 4y and 4y - 8 = 6x so 32 - 4y = 4y - 8 ie 40 = 8y so y = 5 and x = 2

x=7
8+6x = ? 8+6*5 = ? 8+30 = ?
8 = -6x x = -1.3333
