# Aligning the equations [duplicate]

How do I align the two equations and label them?

$$\begin{split} \pd{EU}{\alpha} &= d(\theta) U'(\pi_{1}) [G_{\alpha}(\alpha, \theta, \epsilon) - \widebar{P} C_{\alpha}(\alpha, \theta)] \\ &+ (1-d(\theta)) U'(\pi_{0}) [G_{\alpha}(\alpha, \theta, 0) - C_{\alpha}(\alpha, \theta)] = 0,\\ \end{split}$$
$$\begin{split} \pd{EU}{\theta} &= h'(\theta)[U(\pi_{0}) - U(\pi_{1})] \\ &+ d(\theta) U'(\pi_{1})[G_{\theta}(\alpha, \theta, \epsilon) - \widebar{P} C_{\theta}(\alpha, \theta)] \\ &+(1-d(\theta))U'(\pi_{0})[G_{\theta}(\alpha, \theta, 0) - 1] = 0.\\ \end{split}$$

• At any rate, you want to use the {align} environment from the amsmath package (included in mathtools as well, I think). Can you elaborate on what you mean by 'label'? There are a couple things this could reasonably mean. – Sean Allred May 25 '15 at 6:31
