Two q-supercongruences from Watson’s transformation

Guo and Zudilin (Adv Math, 346: 329–358, 2019) introduced a new method called ‘creative microscoping’, to prove many q-supercongruences in a unified way. In this paper, we apply this method and Watson’s 8ϕ7\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${}_8\phi _7$$\end{document} transformation formula to prove two q-supercongruences, which were recently conjectured by Guo and Schlosser.
