Question

A number is 27 more than the number obtained by reversing its digits. If it’s units and tens digit are x and y respectively, write the linear equation representing the statement.

First answer will be marked branliest, thanks.

Answer 1

Answer:

10y+x+27 = 10x+y

9y-9x=-27

x-y=-3

Answer 2

Answer:

The linear equation representing the statement is p - q = 3

Step-by-step explanation:

Step 1:

If its unit's and ten's digit are p and q respectively.

Total original number is 10q + p  

The new number is obtained after reversing the order of digits is 10p + q  

Step 2:

According to question

⇒ 10q + p = 10p + q + 27

⇒ 9q – 9p = 27

⇒ q - p = 9

⇒ q - p + 3 = 0

⇒ p - q = 3
