(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
If you mean: 2x-3 = 3x+3 then x = -6
6
3(x+2) = x -18 3x+6 = x -18 3x -x = -18 -6 2x = -24 x = -12
If 3x - 9 = -6 then 3x must equal 3. Therefore x = 1 !
3x=18 x=18/3 x=6
First of all, if 'x' is 3, then 'x' doesn't equal -3x+3 . You must mean y = -3x + 3.If x=3, then (-3x + 3) = -6 .The graph is the point (3, -6) .
3x + 18
That factors to (x - 6)(x + 3) x is less than or equal to -3, 6
3x + 7 = -3x 6x = -7 x = -7/6
Presumably it is equal to zero and you want to know the value(s) of x... Factors are (3x + 6)(x - 3) making x either -2 or 3.
3(x + 2) = x - 18 3x + 6 = x - 18 3x - x = -18 - 6 2x = -24 x = -12
3x-3 = 6 3x = 6+3 3x = 9 x = 3
We have, f(x) = x2-3x-18 f(x) = x2-3x-18 = x2-6x+3x-18 = x(x-6)+3(x-6) = (x+3)(x-6) Factors are (x-6) and (x+3).
x2 + 3x - 18 = x2 + 6x - 3x - 18 = x(x + 6) - 3(x + 6) = (x + 6)(x - 3)
x + 3 = 9Therefore, x = 9 - 3x = 6
