Put a digit in the gap, such that the answer is a whole number:

9x-42=5 ... I will give brainiest

9x-42=5 is x = 11.

Step-by-step explanation:

9x - 42 = 5 ...

When we put x = 9

then we will get 81 - 42 = 39

put x = 10 then

9 (10) - 42 = 90 - 42 - 48

put x = 11

then 9 (11) - 42 = 99-42 = 57

So x = 11 is the answer.
