Answer 1

Answer:

let ist digit = X

second digit = y

according to question

X+y = 8 -------------------- equation 1

X-y = 6 --------------------- equation2

X+y =8

x = 8-y ------------------ equation 3

put equation 3 in equation 2

x-y = 6

8-y-y = 6

8-2y = 6

-2y = 6-8

-2y = -2

y = 1 ------------- equation 4

put equation 4 in equation 1

X+y = 8

x+1 = 8

X = 7

y =1 , X = 7
