Let x be the value of the number.
Adding 8 in front of it results in a number whose value ie
8e5 + x
Adding 2 at the end results in a number whose value is
10x + 2
So 8e5 + x = 70x + 14
x = 11594

Let x be this 5-digit number..
therefore 8*10^5 + x = 7*(10x +2)
800,000 + x = 70x + 14
69x = 799,986
thus x = 11,594

11594.
Explanation: The number should end with 4 if you multiply a number ending with 2 by 7.
Start constructing the number by multiplying 42 by 7:
42 * 7 = 294
942 * 7 = 6594
5942 * 7 = 41594
15942 * 7 = 111594
115942 * 7 = 811594

It's 11594
811594 = 7 * 115942
Solve the equation:
x + 800000 = (10 * x + 2)
