If: x-9 = 6x+7 then x works out as -3.2
There is insufficient information to answer this question. If you mean, what does x equal for: 9 + 6x = 2x ...then the answer is: 9 = 2x - 6x = -4x ...which is equal to: x = -9/4 If you mean, what does x equal for: 9 + 6x + 2x = 0 ...then the answer is: 8x = -9 ...which is equal to: x = -9/8
6x-x+15-9= 6x-x=5x 15-9=6 5x+6=0 5x=-6 x=-1.2
x2 + 6x + 9 = 81 x2 + 6x = 72 x2 + 6x - 72 = 0 (x+12)(x-6) = 0 x= -12, 6 (two solutions)
0.2x + 6x - 1 = -9 6.2x = -8 x = -1.2903225806451612903225806451613

x^2-6x+9 (x-3)(x-3)
5x + x - 6x + 2x = 2x
-6x+9 = 45 -6x = 45-9 -6x = 36 x = -6
x2-6x+9 = (x-3)(x-3) when factorised.
5x^2 + 6x + 9 + (?) = -x^2 +3x + 3 (?) = -5x^2 -6x - 9 -x^2 +3x + 3 = -6x^2 -3x -6 Ans: -6x squared +3x -6
(3x - 7)(2x + 9) = 0 x = 7/3 or -9/2
2x + 9 = 6x + 1 9 - 1 = 6x - 2x 8 = 4x x = 2
3+6x = 4x+9 6x-4x = 9-3 2x = 6 x = 3
To factorise this completely you need to be aware that 216 = 63. (x3 + 216) = (x + 6)(x2 - 6x + 36)
7x + 9 = 6x + 17 7x - 6x = 17 -9 x = 8
