One number is 4 more than another, and their sum is 60. what is the smaller number?
if x = the larger number and y = the smaller number, then which of the following systems could be used to solve the problem?

a) x + y = 60 and -x + y = 4
b) x + y = 60 and x - y = 4
c) x + y = 60 and x + y = 4

Option: B is the correct option.

      B)      x + y = 60    and      x - y = 4

Step-by-step explanation:

Let one  number is " x " ; which is also the larger number.

and the other number be " y " ; which is the smaller number.

Also, we are given that:

This means that  the difference of a smaller number from a larger number gives the value  "4"

               Hence, we get that:

                             x-y=4

and also we are given that:

                    This means that:

                            x+y=60

     Hence, option: B is the correct option.
