Question

The sum of two consecutive odd integers is 128. find the two integers.

Answer 1

 Call the first odd number x. 
That means the next odd number would be x+2. 
For example, if the first odd number is 9 then the next one would be 11, which is why it is plus 2. Okay? 

So then, x+x+2=128 
2x+2=128 
2x=126 
x=63 
x+2=65 
Thus, the two consecutive odd numbers are 63 and 65. 

Hope I helped :)

Answer 2

Let's make an equation where y is the largest number.
x+y=128
Since odd consecutive numbers are two away, we can make an equation for y.
x+2=y; let's plug that in for y in the first equation.
x+x+2=128; let's add like terms.
2x+2=128; let's subtract 2.
2x=126; let's divide.
126÷2=63=x
If x is 63, y is 65.
So the two numbers are 63 and 65.
