let the 10 digit number be x
let the one digit number be y
x + y = 14 , y= 14 - x
original number 10x + y
reversed number 10y + x
equation 10y +x = 10x +y +36
subsitute for y
10(14-x) + x = 10x +14 - x + 36
140 - 10x + x = 10x +14 - x + 36
x = 5 y = 14 - x
y = 14 - 5 = 9
original number is 10x + y
10(5) + 9 = 59
let the one digit number be y
x + y = 14 , y= 14 - x
original number 10x + y
reversed number 10y + x
equation 10y +x = 10x +y +36
subsitute for y

140 - 10x + x = 10x +14 - x + 36

y = 14 - 5 = 9
original number is 10x + y
10(5) + 9 = 59
