Question

Find two consecutive odd integers whose sum is 36.

Which of the following equations could be used to solve the problem?
x 2 + 2 = 36
2x + 2 = 36
2x = 36
2x + 1 = 36

Answer 1

C. 2x = 36

Explanation:

We can figure out that

x + x+ 2 = 36

Which leads to much similar answer being;

2x +2 = 36

Which = C. 2x = 36 is correct

Answer 2

2x + 2 = 36. Don't take the answer first, LEARN!

Explanation:

Let's assume the first odd integer to be x. Then, the next consecutive odd integer would be x + 2.

According to the problem, the sum of the two odd integers is 36.

So, we can set up an equation as follows:

x + (x + 2) = 36

Simplifying the left side, we get:

2x + 2 = 36

Subtracting 2 from both sides:

2x = 34

Dividing by 2:

x = 17

So, the first odd integer is 17, and the next consecutive odd integer is 19.

Therefore, the correct equation to solve the problem is:

2x + 2 = 36
