Answer:

The number is 5.33

Step-by-step explanation:

Let the number be x

According to question,

Twice a number is increased by two more than the number and three is equal to 21

Twice a number = 2x

It is increased by two more than number and a three , That is,

2x + x + 2 + 3 = 21

3x + 5 = 21

3x = 21 - 5

3x = 16

Dividing both the sides by 3:

3x / 3 = 16 / 3

x = 5.33

Hence,

The number is 5.33
