Answer:
x=8
Step-by-step explanation:
Cause 8+1 =9
For all the non-negative numbers, the absolute value is always equal to the actual number.
If "x" is any non-negative number, then:
|x| = x
For all negative numbers, the absolute value is equal to -1 multiplied to that number.
If x is any negative number, then:
|x| = -x
So, if after subtracting 2 the number is not anymore equal to it absolute value, this means when 2 is subtracted the number changes from positive to negative.
Only one such number exists that changes from positive to negative on subtraction of 2 and that number if 1.
Absolute value of 1 is 1.
When 2 is subtracted from 1, the result is -1. The absolute value of -1 is also 1. So the absolute value is no longer equal to the original value.
The possible number that satisfies the given condition is 1.

Answer:
4x-13
Step-by-step explanation:
Let the number is x.
We know that triple of a number is 3 times that number i.e. 3x
The difference between triple the number and thirteen 3x-13
Now, we need to add a number to the difference between triple the number and thirteen. So, the expression can be written as :
x+3x-13 = 4x-13
Hence, the expression is (4x-13).
