How could I write down this equation in latex. As a editor I am using overleaf.
Thank you in advance.

Are you maybe looking for the following?
\documentclass{article}
\usepackage{amsmath} % for \text macro
\usepackage{amssymb} % for \mathbb macro
\begin{document}
\begin{equation}
\{ u_t(x,t)=u_{xx}(x,t)\}, \text{ where $\epsilon\in\mathbb{R}$ and $t>0$}
\end{equation}
\end{document}
Alternatively, might you be looking for the following?
\documentclass{article}
\usepackage{amsmath} % for \text macro
\usepackage{amssymb} % for \mathbb macro
\begin{document}
\begin{equation}
u_t(x,t)=u_{xx}(x,t), \text{ where $x\in\mathbb{R}$ and $t>0$}
\end{equation}
\end{document}
Something like this?
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{equation}
\left.\kern-\nulldelimiterspace
\begin{aligned}
\tan(\alpha) &= \frac{h}{x} \\
\tan(\beta) &= \frac{h}{d - x}
\end{aligned}
\right\}
\text{First step}
\end{equation}
\end{document}
Package amsmath provides aligned for equations systems inside an equation line. Then also \dfrac is not needed and \frac suffices.
There is also environment rcases of package mathtools, but it is not used here, because of the additional alignment.

Generally I use for a better alignment of a function assignment
\mathrel{\mathop:}. Tou can see "The Comprehensive LATEX Symbol List of Scott Pakin (19 January 2017)" at page 49.Here my MWE:
