Question

(10x+y) - (10+x) = 27
value of y and x​

Answer 1

Answer:

let the given number = 10x + y

x + y = 9 -------------(1)

10x + y + 27 = 10y + x

10x + y - 10y - x = - 27

9x - 9y = -27

divide by 9

x - y = -3 ------------(2)

on adding eq 1 and 2

x + y = 9

x - y = -3

2x = 6

x = 6/2

x = 3

put x in eq 1

x + y = 9

3 + y = 9

y = 9 - 3

y = 6

then given number is 10x + y

= 10 × 3 + 6

= 30 + 6

= 36

Answer 2

Answer:

10x+y-10-x=27, 10x-x+y=37, 9x+y=37,x+y=37/9=4.1, x+y=4.1, replace x = 4.1-y in 9x+y=37= 9(4.1-y)-y=37,36.9-9y+y=37 , -8y=0.1, y=0.1/-8
