Let the tens place digit be a
And Unit place digit be b
According to first condition,
a - b = 6 ---------(1)
According to second condition,
10b + a + 10a + b = 88
=> 11a + 11b = 88
=> a + b = 8 ------(2)
On adding equation 1 and 2, we get
2a = 14
=> a = 7
Now,
On Substituting the value of a in equation 1, we get
7 - b = 6
=> b = 1
Required number = 71
And Unit place digit be b

Answer:
71
Step-by-step explanation:
Tens place = x , units place = y
x - y = 6 (1)
10y+x+10x+y = 88 ---> 11x+11y = 88
x + y = 8 (2)
Adding equation (1) and (2),
x - y = 6
x + y = 8
-------------
2x = 14 -----> x = 7
7 - y = 6 ---> y= 1
Therefore, required number is 71.
