Which three expressions could be used to represent the numbers?

n; n - 4; 4n

n; 4 - n; n + 4

n; n/4; n + 4

Answer 1

The first one, this is because you must have: the original: n 
                                                                            the ori- 4    : n-4
                                                                            the ori*4     : 4n
