Two consecutive odd integers are known as back-to-back odd whole numbers; one right after the other.
For example; 1 and 3, 3 and 5, 5 and 7, and so on. Let’s work up to which two consecutive odd integers make a product of 63.
1 x 3 = 3; no
3 x 5 = 15; no
5 x 7 = 35; no
7 x 9 = 63; yes

From the work shown above, we can see that the two consecutive odd integers “7” and “9” make a product of 63.

I hope this helps!

Answer:

Step-by-step explanation:

t + u = 11 ----------- (1 )

10t + u = 10u + t - 9

10t + u - 10u - t = -9

10t - t + u - 10u = - 9

Combine like terms

9t - 9u = -9

Divide the entire equation by 9

$\dfrac{9}{9}t-\dfrac{9}{9}u=\dfrac{-9}{9}$

t - u = -1 --------------(2)

Add equation (1) & (2) and so, u will be eliminated and we can find the value of t

(1) t + u = 11

(2) <u>t - u = -1</u>

2t = 10

t = 10/2

t = 5

Plugin t = 5 in equation (1)

5 + u = 11

u = 11 - 5

u = 6

The original number is 56
