Question

Find two consecutive odd integers whose sum is 36. Which of the following equations could be used to solve the problem?

1. 2x = 36
2. 2x + 1 = 36
3. 2x + 2 = 36
4. x2 + 2 = 36

Answer 1

Let, the integers are: x, x+2

Them, x + x+ 2 = 36
2x +2 = 36

In short, Your Answer would be Option C

Hope this helps!

Answer 2

3.
`2x+2=36`

Explanation:

Let the first odd integer = x

Then, the consecutive other odd integer = x+2.

Then, according to the question, we have,

Sum of both the integers = 36.

i.e.
`x+x+2=36`

i.e.
`2x+2=36`

Thus, the equation to solve the problem is
`2x+2=36`.

Hence, option 3 is correct.
