the tens digit = n
the units digit = n-5

n + n-5 = 9
2n = 9+5
2n = 14
n = 7  ←  the tens digit

the units digit = n-5 = 7 - 5 = 2

the number is 72

Answer: 72

Step-by-step explanation:

Let x represents the units digit of the number, then the value of tens digit will be [tex]x+5[/tex].

According to the question , we have the following equation:-

[tex]\Rightarrow\ x+x+5=9\\\\\Rightarrow 2x+5=9[/tex]

Subtract 5 on both sides , we get

[tex]2x=4[/tex]

Now, Divide 2 on the both sides , we get

[tex]x=2[/tex]

Now, the unit digit of the number = 2

The tens digit of the number = 2+5=7

Then , the number will be : 72
