If you mean: -2(3x-3) = 7x-2 then the value of x works out as 8/13

I think you mean (3x ± 1)^2 = (3x+1)(3x-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.
3x=2 Divide the x over and you get 3 divided by 2 x=3/2
If: 15+3x = 6x-2 Then: 15+2 = 6x-3x => 17 = 3x Therefore: x = 17/3 or 5 and 2/3 as a mixed number
In the equation 3x plus 7 equals 13, x is equal to 2.
