7*(2*x - 16), or maybe 7*| 2*x - 16 |. It depends on if you want to keep the 'difference' to be a positive number.
They are 4 and 7.
8(x - 7)
The difference is 90000000
7x - 8 = 2 7x = 10 x = 10/7
7/ 3/
18
7
The difference between 7 times the last digit and the rest of the number is a multiple of 71
7*(2*x - 16), or maybe 7*| 2*x - 16 |. It depends on if you want to keep the 'difference' to be a positive number.
They are 4 and 7.
3 x (7 - n)
8(x - 7)
Not necessarily. The difference between a = 7 & b = 7 is 0, and that is not a natural number.
The difference is 90000000
8(x-7)
7x - 8 = 2 7x = 10 x = 10/7
