I want to write following system of equation in my paper, but I don't know how:
enter image description here



Here is a code that I've tried, but it does not work:



Rgeqslant R_t equiv begin{cases} frac{r_{t+1} (1-W(k_t)}{f'(k{t+1}    
lambda} &mbox{if } k_t < K(lambda) \
frac{r_{t+1}}{f'(k_{t+1})} & mbox{if } k_tgeqslant K(lambda)
end{cases}


Any suggestions will be very helpful. Thanks

Welcome to TeX.SE. Here my (fast) proposal from your original code:



enter image description here



documentclass[12pt]{article}

[Rgeqslant R_t equiv begin{cases} dfrac{r_{t+1} (1-W(k_t))}{f'(k{t+1}

&\
dfrac{r_{t+1}}{f'(k_{t+1})} & mbox{if } k_tgeqslant K(lambda)
end{cases}]
end{document}


EDIT: By correct comment of @Yorgos:
