x+x+x= 3x
If you mean: (3x-1)(x+1) = 0, then it is 3x squared+2x-1 = 0. Its solutions are: x = 1/3 or x = -1.

3x - 3x -1 + 2x -1 = 0 0 - 1 + 2x - 1 = 0 2x - 2 = 0 2x = 2 x = 1
9x2 + 18x - 16 = 0 ⇒ (3x - 2)(3x + 8) = 0 ⇒ 3x - 2 = 0 → x = 2/3 or 3x + 8 = 0 → x = -22/3
2x minus 3x is equal to -x.
3x = 7-5x 8x=7 x = 7/8 x = 0.875
3x=18 x=18/3 x=6
x is -93.
2x minus 3x is equal to -x.
If 3x - 9 = -6 then 3x must equal 3. Therefore x = 1 !
X= -2 ! Since the equation must equal zero - 17+3x must equal 11. The variable 3x HAS to equal -6... therefore x is equal to minus 2.
It is equal to 21x You can not find x.
You need an equal sign to solve for x.
3x = x+8 so 3x-x = 8 hence 2x = 8 and so x = 4
x+x+x= 3x
If you mean: (3x-1)(x+1) = 0, then it is 3x squared+2x-1 = 0. Its solutions are: x = 1/3 or x = -1.
