Can someone help me on this

Answer:
Two (2) terms
Step-by-step explanation:
ALWAYS remember a term is a part of an algebraic expression that is separated by addition.
The expression here is quite simple: [tex]x = y - z[/tex]
But remember what I explained above; therefore, the expression would be written like this: [tex]x= y + (-z)[/tex]
giving you two (2) terms.
Hope this helps!
