6x-4+7=-5 6x+3=-5 6x=-8 x=-8/6 = -4/3
It is: 3x2+6x-11 = 0
6x+4=3x+12 => 6x-3x=12-4 => 3x=8 => x=8/3=2.666...
The answer to -6 plus 8 take away 7 plus 3 equals -2. This is taught in math.
Given 6x + (7x-8) = -5 6x + 7x - 8 = -5 ==> 13x = 3 therefore, x = 3/13
6x-4+7=-5 6x+3=-5 6x=-8 x=-8/6 = -4/3
It is: 3x2+6x-11 = 0
6x+4=3x+12 => 6x-3x=12-4 => 3x=8 => x=8/3=2.666...
6x + 8 = 6 6x = -2 x = -2/6 x = -1/3
The answer to -6 plus 8 take away 7 plus 3 equals -2. This is taught in math.
Given 6x + (7x-8) = -5 6x + 7x - 8 = -5 ==> 13x = 3 therefore, x = 3/13
6x+3y = 8 3y = -6x+8 y = -3x+8/3 The slope of the line is -3
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)
2x-4=6x+8-8= -82x-12= 6x-2x= -2x-12= 4x/4=/4-3=x
6x + 8 = 13, 6x = 13 - 8, 6x = 5, x = 5/6
y=6x-16 y=-2x+8
