. If 5 is subtracted from 5 times a number, the result is 40. Find the number.
2. Find two consecutive odd numbers whose sum is 644.​

Answer 1

Answer:

1. The Number is 9

2. Numbers are 321 and 323

Step-by-step explanation:

( 1) Let the number be X

Therefore 5X-5=40

5X=40+5

5X=45

X=45/5

X=9

(2). The two odd numbers be X and X+2

Hence, X+X+2=644

2X+2=644

2X=644-2

2X=642

X=642/2

X=321 and X+2=323
