Answer:
Step-by-step explanation:
I'm assuming this is for choir, so what you need to do is know your "keys" such as, F Major, F Minor, etc. and start writing your solfege on where the note starts. Such as for the key of F Major, the key starts at the f note so you put your 'do' there and go up one by one and fill in your solfege.
You write your solfege down in whatever key it says, and then at the other part, you're supposed to write down do, mi, so, high do, and then go back down the same notes.
Hope this helps!
