try to use this code:
$$
\begin{align}
h(x) =& \frac{1}{\int_xt(x)\mathrmu0z1t8osx} \tag{1}\\
f(x) =& \frac{1}{\int_x\eta(x)\mathrmu0z1t8osx}g(x)\tag{2}
\end{align}
$$
and it will look like this below:
公式1
or like this code
$$
\begin{align}
a &= b + c \tag{3}\\
&= d + e + f\tag{4}
\end{align}
$$
and we will get equations below:
公式2

try this code:
$$
\begin{eqnarray}
a & = & b + c \\
& = & d + e + f + g + h + i
+ j + k + l\\
&& +\: m + n + o \\
& = & p + q + r + s
\end{eqnarray}
$$
and we will get things like this:
