Question

5) Express the statement as a linear equation in two variables: the sum of a two digit no and the number obtained by reversing the order of its digits is 121

​

Answer 1

Answer:

the linear polynomial can be 10x+y=121

hope this will help you..

Answer 2

Let the unit digit are x & y

Then the number be 10x+y

On reversing the order the number is 10y+x

Then the condition that given in the question is

(10x+y)+(10y+x)=121

11x + 11y =121

11(x+y)= 121

x+y=11

Therefore the linear equation must be x+y=11

Hope this helps you friend
