Suppose it is x.
Then x + 1.6 = 9
Subtract 1.6 from both sides: x = 9 - 1.6 = 7.4
There is no selected number so it would be a variable. The answer is 2n-9 (n is the number which you choose)

16+2x=-56 -56-16=2x -72=2x x=-72/2 x=-36
That sounds like: if you multiply it by 16, the result is the same as if you add 225 to it. You can write this as an equation - calling the number "x" - as follows: 16x = x + 225 Solve this equation, and you have your number.
103.4 increased by 16% = 120
9+b increased simply means addition.
It is: 10+(-1) = 9
There is no selected number so it would be a variable. The answer is 2n-9 (n is the number which you choose)
-5
16
...so the number is 10 less than 16. Can you work it out now...?

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)"
36 has nine factors.
28 .5 x 28= 14 14 + 2= 16
