The LCD in this equation is (x+2)
Multiplying the LCD to both sides, we got:
3x=-6-2(x+2)
Distribute -2 to (x+2), we got:
3x=-6-2x-4
Now, transfering
3x+2x=-6-4
5x=-10
divide both sides by 5
we got: x=-2
Checking:
3(-2)/(-2+2)=(-6)/(-2+2)-2
(-6)/0=(-6)/0-2
undefined=undefined-2
undefined=undefined
Note that in checking, there appeared a zero (0) denominator. Making a term undefined. However, the argument reamins valid because subtrating anything from undefined remains undefined. So don't wonder where the -2 in above solution went so that undefined=undefined

3x/(x+2) = -6/(x+2) -2
Multiply both sides by (x+2) to get rid of the fractions
3x = -6 -2(x+2)
Multiply out the bracket
3x = -6 -2x -4
Tidy up
5x = -10
x=-2

x = -2
However, its one of those flawed questions as when you substitute x = -2 into the equation, you find that the denominator becomes 0! In which case, there is no solution if the questions is given in this form. If the question given is (3x) = (-6) - 2(x+2), then x=-2 would be legitimate.

Value for x xould not be determined. Refer to your Algebra.

x = - 2
You need to multiply everything by x + 2. You will then see what you need to do...I hope.
