Let the one digit be x
other digit =8-x
No.=10(8-x)+1(x)
80-10x+x
80-9x
Reversed no.= 10(x)+1(8-x)
10x+8-x
9x+8
Alq,
80-9x+18=9x+8
-9x-9x=8-80-18
-18x=8-98
-18x=-90
x=-90
-18
x=5
Hence, the one digit = 5
other digit = 8-5
= 3
other digit =8-x
No.=10(8-x)+1(x)
80-10x+x
80-9x
Reversed no.= 10(x)+1(8-x)
10x+8-x
9x+8
Alq,
80-9x+18=9x+8
-9x-9x=8-80-18
-18x=8-98
-18x=-90
x=-90
-18
x=5
Hence, the one digit = 5
other digit = 8-5
= 3
