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.
If 2 divided by 3x it is equal to 2/3x
3x^2

eq: 3x+5=7 =3x=7-5 =3x=2 =x=2/3

y = -1x/2 3x + 6y = 0 -3x -3x __________ 6y = 0 - 3x --- -------- 6 6 y= -3x/6 y= -1x/2
3/2
(x-4)(3x-2)/(x-4) is equivalent to 3x-2 except when x=4.
3x+2y-7=0 2y=-3x+7 y=1/2(-3x+7) or -3/2 x +7/2
-66.
