The question cannot be answered because it is ambiguous.
Does "twice the sum of 16 and a number" mean "2*16 + x" or does it mean "2*(16 + x)"
2x - 4 = 6x -4 = 4x x = -1
Whatever the variable was.
Yes.
The sum of four times a number and twice the same number can be represented mathematically as (4x + 2x), where (x) is the number. Combining the terms, this simplifies to (6x). Therefore, the result is six times the number.

Nine less than twice a number equals the same number increased by four?
2x - 4 = 6x -4 = 4x x = -1

I guess you could use a search engine or maybe one of the address designators: but guess whatt???? Try it twice, or more!! Bet you do not come up with the same number twice.

If you can use the same number twice, such as 11 or 22, then there are 100 possible numbers (00, and 01-99). If you can not use the same number twice, the answer is 90.
