# Equation number alignment error

This equation number is in chapter 3, so when it comes like 3.45 in front of the equation, then no space with the equation and the equation number

\begin{eqnarray}
A_{1}r^{-(g_{0}(z)+g_{1}(z,\lambda))/B} \bigg(\frac{d g_{0}}{g z} +\frac{g g_{1}}{g z}\bigg) + (B_{2}+C_{c})r^{-(c_{0}(z)+c_{1}(z,\lambda)+f_{2}(z))/k}\bigg(\frac{d f_{0}}{d y} +\frac{d f_{1}}{d z}+\frac{d f_{x}}{d z}\bigg)-ccf=0 \nonumber  \\
(1+ggr^{f_{2}(b)/rr}) \bigg(\frac{d f_{gg}}{d z} +\frac{d f_{1}}{dhh}\bigg) +\frac{d f_{2}}{d z}-ff=0 \label{mmm6}
\end{eqnarray}

Stop using eqnarray use align from amsmath. AMS tracks the width of the equation number and move it out of the way if necessary, eqnarray obviously does not.
For more info as to why one should not use eqnarray see:
