So, I'm typing away as follows:
This does not seem to compile correctly on Mathjax, but it compiles in my $\LaTeX$ environment. My problem is this: I want Problem 38's text to begin aligned with the y_{1} of the previous line and on the same line as the number 38, but I don't want the preceding align environment to push everything over to the right, just because I now have a huge amount of text to format. I like the intertext command for inserting text into an align environment. What I essentially need now is a way to "ignore" alignment for the rest of one line, after I've done one or two ampersands for the first alignments. Is there a way to do that?
Code:
