The number is 5.

Step-by-step explanation:

Let,

x represent the unknown number.

According to given statement;

add five to twice a number the results is fifteen

2x + 5 = 15

Subtracting 5 from both sides

[tex]2x+5-5=15-5\\2x=10[/tex]

Dividing both sides by 2

[tex]\frac{2x}{2}=\frac{10}{2}\\x=5[/tex]

The number is 5.
