Hi i am confused as to how to calculate the age of the universe with redshift(adsbygoogle = window.adsbygoogle || []).push({});

say for example

The age of the universe now is 13 billion years old (and a critical universe).

How do i find the age of the universe if it was a redshift at say 10??

Do i have to find the scale factor first?

I am not very sure, please help!!
