Linear Equatlions in One Variablehe digits of a two-digit number is9.

1.	Linear Equatlions in One Variablehe digits of a two-digit number is9. When we interchange the digits,it is found that the resulting new number is greater thaninal number by 27. What isthe two-digit number?8.17
Answer» Let’s say x is the unit digit and y is the tenth digit. y+x = 9 -> y=9-x 10x+y = 10y+x+27 10x+9-x = 10(9-x)+x+27 10x+9-x = 90–10x+x+27 18x = 108 x = 6 so y = 3 let’s check 63 - 39 =27 27 = 27 (correct) sorry your is not right

Answer»

Let’s say x is the unit digit and y is the tenth digit.

y+x = 9 -> y=9-x

10x+y = 10y+x+27

10x+9-x = 10(9-x)+x+27

10x+9-x = 90–10x+x+27

18x = 108

x = 6

so y = 3

let’s check

63 - 39 =27

27 = 27 (correct)

sorry your is not right
