If you mean: 3x+2 = 8 then x = 2
(x - 3x - 6) / 6 = (3x + 2) / 2 ∴2(3x + 2) = 6(3x + 2) ∴6x + 4 = 18x = 12 ∴12x = -8 ∴x = -2/3
6x + 6 = 3x - 2 Bring 3x to the left and subtract: 6x - 3x = 3x 3x + 6 = -2 -2 - 6 = -8 -8 / 3 X = -8/3
6x - 12 = 3x + 12 Add twelve to both sides.6x - 12 + 12 = 3x + 12 + 12Simplify.6x = 3x + 24Subtract 3x from both sides.6x - 3x = 3x + 24 - 3xSimplify.3x = 24Divide both sides by 3.x = 8The answer is x = 8.
3x3 + 6x2 - 24x = 3x(x2 + 2x - 8) = 3x(x2 + 4x - 2x - 8) = 3x[ x(x + 4) - 2(x + 4) ] = 3x(x - 2)(x + 4)
12 + 3x = 412 - 12 + 3x = 4 - 123x = -83x/3 = -8/3x = -8/3x = -(2 2/3)
3x = -12 so x = -4
3x+8 = 12 3x = 4 x = 4/3
3x + x + 8 = 204x + 8 = 204x = 12x = 3
6x+4=3x+12 => 6x-3x=12-4 => 3x=8 => x=8/3=2.666...
3x + 8 = 20 3x = 20 - 8 3x = 12 3x = 12/3 x = 4
6x - 3x = 5x - 10x + 12 6x - 3x - 5x + 10x = 12 8x = 12 8x/8 = 12/8 x = 12/8 = 3/2 x = 1.5
8+7x = 20+3x 7x-3x = 20-8 4x = 12 x = 3
If you mean: 3x+2 = 8 then x = 2
-3x+2 = 2x-8 8+2 = 2x+3x 10 = 5x x = 2
11x + 8 = 8x + 20 3x + 8 = 20 3x = 12 x = 4
(4x ^2 + 3) + (3x ^2 + 8) = ( 4x^2 + 3x^2 ) + (3+8) = 7x^2 + 11
