Answer:
2x + y = 8
Step-by-step explanation:
if 7- digit number 134x58y is divisible by 72 then the value of (2x+y)
134x58y is divisible by 72
=> 134x58y is divisible by 8 & 9
134x58y is Divisible by 9 if sum of digits is divisible by 9
=> 1 + 3 + 4 + x + 5 + 8 + y is divisible by 9
=> 21 + x + y is divisible by 9
=> x + y = 6 or x + y = 15
134x58y is divisible by 8
if 58y is divisible by 8
=> 584 is divisible by 8
=> y = 4
so x + y = 15 not possible
hence x + y = 6
=> x = 2
2x + y = 2*2 + 4 = 8
2x + y = 8
