One number is 5 more than another.
their sum is 53. what are the two
numbers?
make a record of how you solved.

  24 and 29

Step-by-step explanation:

Let x represent one of the numbers, then the other number is x + 5.

"sum" means to add them, so lets add x and x + 5 and set it equal to 53

   x    +     x + 5    = 53

             2x + 5    = 53           simplified

             2x          = 48           subtracted 5 from both sides

               x          = 24            divided 2 from both sides

So one of the numbers is 24.    The other number is    x + 5  

                                                                                  =   24 + 5

                                                                                  =      29
