You can simplify it but you cannot solve it as it is not an equation.
----------------
Factor to get:
[3x(3x+2)]/12x
Cancel the common factor of "3" to get:
[x(3x+2)]/x

You can put this solution on YOUR website! (9x^2 + 6x)/12x
the numerator can be factored as follows:
(9x^2 + 6x) = x * (9x + 6) = 3x * (3x + 2)
the equation becomes:
3x * (3x + 2)/12x
the x in the numerator and denominator cancel out:
3 * (3x + 2) / 12
the 3 in the numerator divides into the 12 into the denominator so the equation becomes:
(3x + 2)/4

i think that's as far as you can go.
is the simplification valid?
try substituting in the original equation and in the simplified equation.
let x = 2
(9x^2 + 6x) / 12 x becomes:
36 + 12) / 12 * 2
48/24

in the simplified equation:
let x = 2
(3*2 + 2)/4
(6 + 2)/4
8/4

since both the original equation and the simplified equation yield the same answer, then the simplification is good.

i think that's you can't go any further than that.
so the simplified form would be:
(3x+2)/4
