# Manually break an equation chain and adjust indentation

If an equation chain is too long I normally spit the chain in the following way

$$\begin{split} x&=y\\&=z\\&=w \end{split}$$


However, if x takes too much horizontal space, I would like to introduce a break immediately after x, insert 12 blanks and then insert y. The other breaks (afer y and after z) should still be there and each new line should be indented by 12 blanks. How can I do this?

• I think what you want is align. Look for it. – Sigur Jun 24 at 13:59
• Please provide more realistic MWE, which will show what you like to achieve. Some sketch of desired result also be helpful. – Zarko Jun 24 at 14:04

Sounds like your are looking for \MoveEqLeft from the mathtools package:
\documentclass{article}
$$\begin{split} \MoveEqLeft \rule{5cm}{1.5ex} \\ &= \rule{6cm}{1.5ex} \\ &= \rule{4cm}{1.5ex} \\ &= \rule{2cm}{1.5ex} \end{split}$$
