8+6x = ? 8+6*5 = ? 8+30 = ?
6x-4+7=-5 6x+3=-5 6x=-8 x=-8/6 = -4/3
6x = 32 - 4y and 4y - 8 = 6x so 32 - 4y = 4y - 8 ie 40 = 8y so y = 5 and x = 2
Given 6x + (7x-8) = -5 6x + 7x - 8 = -5 ==> 13x = 3 therefore, x = 3/13
6x+4=3x+12 => 6x-3x=12-4 => 3x=8 => x=8/3=2.666...
6x + 8 = 13, 6x = 13 - 8, 6x = 5, x = 5/6
8+6x = ? 8+6*5 = ? 8+30 = ?
6x - 8 + 2x - 5 = 7 - 2x ?
6x-4+7=-5 6x+3=-5 6x=-8 x=-8/6 = -4/3
6x = 32 - 4y and 4y - 8 = 6x so 32 - 4y = 4y - 8 ie 40 = 8y so y = 5 and x = 2
Given 6x + (7x-8) = -5 6x + 7x - 8 = -5 ==> 13x = 3 therefore, x = 3/13
6x+4=3x+12 => 6x-3x=12-4 => 3x=8 => x=8/3=2.666...
3x - 8 = 7 so x = 5
The quadratic expression x2+6x+8 when factorised equals (x+2)(x+4)
6x + 8 = 6 6x = -2 x = -2/6 x = -1/3
y=6x-16 y=-2x+8
6x-8+2x-5 = 7-2x 6x+2x+2x = 7+8+5 10x = 20 x = 20/10 x = 2
