The sum of two consecutive integers is 59. Write an equation that
nata0808 [166]
Let the smaller of the two numbers be x. Therefore the larger number is 1 bigger, x+1.

x + (x + 1) = 59
We can solve this equation for x, which will be one of our two numbers.
2x + 1 = 59
2x = 58
x = 29
Now that we've found x, we can find x + 1. In this case, x + 1 = 29 + 1 = 30.
Therefore, the two numbers are 29 and 30.
