I know how I can align an equation to the left with flalign*. And I also know how to have an equation with multiple "tabstops" (I don't know what else to call it) using align* with &&. But I can't get both: An equation at the left with multiple tabstops. What I want is about this, but on the left:
A = abc*2 + jkl
= a + kdjfk
Notice that "+" and "=" are both aligned. Can anyone tell me how to do that in LaTeX? I have searched for a while by now but didn't find anything.
