5x + x - 6x + 2x = 2x
6x
The quadratic expression x2+6x+8 when factorised equals (x+2)(x+4)
If: 9x+7 = 6x+25 Then: x = 6
x=10
-6x
6x+4 = x+12+4x-6 6x-x-4x = 12-6-4 x = 2
If: x-9 = 6x+7 then x works out as -3.2
6x plus 3 equals 8x plus 14 when solved mathematically is equal to x = -5.5.
x=3 becaus: 6x=x+15 5x=15 (-x) x=3 (divided by 5)
6x+4=52 6x=48 x=8
x=-3
