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.
If: 16+2x = 36 then the value of x works out as 10
It does not mean anything at all. "Twice a number" is only one number while "the difference" must refer to two numbers, not just one.

if a number is "x" then it is 2x-16
The expression is: 2x-16
twice the difference of three times a number and eight
The difference between a number x and twice y is equal to fifteen.
If: 16+2x = 36 then the value of x works out as 10

One number is eight more than twice another if their difference is 25. The larger number is 42
Twice the number is something like 3x2, 4x2.... Squared is 3x3, 4x4. It's one number multiplied by itself twice
Twelve. Four squared is sixteen less four is twelve.
