The sum of two numbers is 51. The smaller number is 5 less than the larger number. What are the numbers?
We know that the two numbers add to 51, let's call them x and y
And we know one number is 5 less than the other
We can equate these two eqations
Now we know x is 23, we can find y.
So the numbers are 28 and 23.
Hope this helps!
