You find x. Oh! There it is!! ^ See?
12x - 6 = 10x +2 12x - 10x = 2 + 6 2x = 8 x = 4
x - 10x = 9x, so 9x + 3 = 0, so 9x = -3 so x = -1/3
-4x+3 = 23+6x -4x-6x = 23-3 -10x = 20 x = -2

There is no symbol between 7x and 31. Please resubmit using words eg "plus", "equals" etc.
10x=x 9x=0 x=0
If: 10X = 2.7 then X = 2.7/10 => 0.27
x - 10x = 9x, so 9x + 3 = 0, so 9x = -3 so x = -1/3
11x = 10x-19 Subtact 10x fromboth sides:- x = -19
12x + 9 = 10x + 1 Subtract 10x from both sides: 2x + 9 = 1 Sutract 9 from both sides: 2x = - 8 Divide both sides by 2: x = -4
-4x+3 = 23+6x -4x-6x = 23-3 -10x = 20 x = -2
x2 + 10x + 21 = (x + 3)(x + 7)
