x = 0
Easy peasy! If the answer is 0 from that algebraic expression then you can automatically say that the variable x = 0 because you can't add, multiply, or divide any number outside of 0 to get 0. I hope that this helps
Answer:
a) Interpretation of the expression
b)
Step-by-step explanation:

And in the three numbers that are given to us there is only one multiple of 5 which is 20 . so, that is why Frank is incorrect.
