I have attached the sample file bellow. I have put many equations in arrays since I want to get multiline equation with single label and align them to the left. But it turned out that elements in the array are not in display style. Finally, I found using aligned AMS environment is what I desired. I just need to put all of them to the second column to get them align left. But situation now is that I have so many equations need to perform this conversion. Could anybody give a suggest on what I shall do to minimize the workload. Thanks in advance!
