unit digit = x
ten's digit = y
no. = 10y+x
no obtained by reversing the digit = 10x+y
according to condition,
10x+y+10y+x = 121
11x+11y = 121
x+y = 11. is the required linear equation.
ten's digit = y
no. = 10y+x
no obtained by reversing the digit = 10x+y
according to condition,
10x+y+10y+x = 121
11x+11y = 121
x+y = 11. is the required linear equation.
