How can I place the equal sign of the second line just below the equal sign of the first line in the following command:



Z = X+Y\\ =\text{A little big line than X+Y}

  • Add a & before each = sign.

Like this?



    Z &= X+Y\notag\\ 
    &=\text{A little big line than X+Y}\label{Eq1} 

Ref: \eqref{Eq1}.
