Answer:
y = 0 and z = 5
Explanation:
the denominator of the expression cannot equal zero as this would make the expression undefined Equating the denominator to zero and solving gives the values that y and z cannot be
solve y(z - 5) = 0
equate each factor to zero and solve
y = 0 ← excluded value
z - 5 = 0 ⇒ z = 5 ← excluded value
