Math & Science ⇒ Alignment in a multi-line Equation

[erictamlam]

Hi all,

I want to type an equation as attached in the image, but not sure which equation environment can achieve the exact outcome, split, align, {eqnarray}, {array}?

Anyone knows? Thanks in advance.

[Stefan Kottwitz]

I would use an align environment if both equations should be numbered, align* if there should not be a number, split within an {equation} environment if both lines should get one number together.

For the expression with the brace, you could use cases.
