Question

3) A number is 18 more than the number obtained by reversing its digits. If its
unit's and ten's digit are 'a' and 'b' respectively, write the linear equation
representing the above statement. Also draw the graph of the linear equation and
write some of its probable answers.​

Answer 1

Answer:

Unit digit = a

Tens digi =  b

Number = 10b + a

==: 10b + a - (10a + b) = 18

==: 10b + a - 10a - b = 18

==: 9b - 9a = -18

==: b - a = -2

Now u can draw the graph with this information
