When 13 is subtracted from the sum of 2 consecutive numbers the answer is 18 what are the consecutive numbers?
Hitman42 [59]
Let x = the first number
x+1 = the second number

The sum of our two numbers is therefore:  x + (x+1)

When you subtract 13 from the above you get 18 left over.

So our equation is:

x + (x+1) - 13 = 18

Now we can just solve for x:

x + (x+1) = 31

2x + 1 = 31

2x = 30

x = 15

So our first number is 15 and our second number must be 16.
