Question

Guys pls help me with this question:-
Q) Sukhdev has written a two digit number where sum of the digits is 6 and the two digits interchange their places if 36 is added to the number..construct simultaneous linear equation and draw graph..

Guys I don't want graph..I want only the equation..​

Answer 1

Answer:

Let the number be 10a + b.

a+b = 6

when we interchange the digits, we get a new number: 10b+a = 10a+b+36

Answer 2

Answer:

a two digit number where sum of the digits is 6 linear equation for this part

let two digits=x and y

sum of digit

x+y=6

the two digits interchange their places if 36 is added to the number

x+36=y

and y+36=x
