Title: Tag each equation in an IVP
Post by: Jingxuan Zhang on February 10, 2018, 04:14:10 PM
I am trying to typeset in latex a system such as
$$\left\{\begin{array}{cc}f(x)&=k_1\\g(x)&=k_2\end{array}\right..$$
Is there anyway that allows me to label each individual equation such as with \tag? True, with align I can label but i need also the brace. True, with array I can brace but then cannot label. Thanks.

There is a package empheq, which allows you to do it in the normal LaTeX

Does not work in MathJax (so far, at least)
