**[SOLVED] Chemistry equilibrium Question**

## Homework Statement

K=64. at 25 degrees celsius

N2(g) + 3H2(g) <--> 2NH3(g)

Molarity N2= .5M H2= 1.5M. what are the equilibrium concentrations?

i got the equilibrium table set up, and the K expression is

(2x)(2x)

k= ------------------------------

(.5-x)(1.5-3x)(1.5-3x)(1.5-3x)

how can i solve for x?
