I'm confused on when to use "y" or "e" for saying "and" in Spanish. Can someone please explain

Y becomes e when it precedes a word that begins with the i sound. Typically, y becomes e when it precedes most words that begin with i- or hi-. O becomes u when it precedes a word that begins with the o sound

Explanation:

in my knowledge ik i would say: te quiero tambien.

you,

travel to mexico,

you would sell things that you don't use anymore.

their's 2 things you could put in your spanish assignment.
