Given command for Hp prime?

[Lord_Spooglypuff]

Hi all.
I have recently switched out my Ti nspire for a hp prime, and I am struggling to figure out how to set restrictions on equations on the CAS.
For example, on the 84 plus and nspire, restricting equations is done using set notation:
eg: solve(v^2=u^2+2a*s)|v=50,u=5
So how would I convert that to hp prime syntax? I have been doing some digging, and I found that the given symbol exists, but I can't figure out how to get it to work without just displaying syntax errors.
Thank you for your help.
