6x + 8 = 20
Subtract 8 from both sides: 6x = 12
Divide both sides by 6: x = 2

∙ 13y agoThe quadratic expression x2+6x+8 when factorised equals (x+2)(x+4)
6x = 32 - 4y and 4y - 8 = 6x so 32 - 4y = 4y - 8 ie 40 = 8y so y = 5 and x = 2
It is 8
X equals to 8
8+6x = ? 8+6*5 = ? 8+30 = ?
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)
Add 12 to each side: 4x + 6x = 20 ie 10x = 20 so x = 2
6x + 8 = 13, 6x = 13 - 8, 6x = 5, x = 5/6
y=6x-16 y=-2x+8
6x+4=52 6x=48 x=8
6x-8+2x-5 = 7-2x 6x+2x+2x = 7+8+5 10x = 20 x = 20/10 x = 2
It is 8
6x = 32 - 4y and 4y - 8 = 6x so 32 - 4y = 4y - 8 ie 40 = 8y so y = 5 and x = 2
X equals to 8

8+6x = ? 8+6*5 = ? 8+30 = ?
