6x plus 3 equals 8x plus 14 when solved mathematically is equal to x = -5.5.
-6x
Given 6x + (7x-8) = -5 6x + 7x - 8 = -5 ==> 13x = 3 therefore, x = 3/13
x=10

6x+x = 7x
6x plus 3 equals 8x plus 14 when solved mathematically is equal to x = -5.5.
-6x
Given 6x + (7x-8) = -5 6x + 7x - 8 = -5 ==> 13x = 3 therefore, x = 3/13
x=10
6x
The quadratic expression x2+6x+8 when factorised equals (x+2)(x+4)
6x+4=52 6x=48 x=8
Given 6x-1 = 29: 6x = 30 x = 5 Therefore x² = 25, adding 25 and 5 gives you 30
It is: 3x2+6x-11 = 0
