The value of A is 9. This is because 40-13= 27
3x?=27 3x9=27
If your looking for the value of "x" it is 4.
Hope this helped!
The answer that you should get is 5.4919
I am not sure what your asking but if it is what i think it is, then a number cant be less than -6 but not less than -3 because -3 is greater than -6. so its impossable (if it is what i think you mean)
