Verified Answer :

The answer must be positive.  Let's say that X = -10.

10-(-10)

The negatives cancel leaving us with a positive number.  Thus every number that X can be will result in a positive answer.

Answer:

the value of x makes the value of the expression positive.

Step-by-step explanation:

The value of x is negative.

\(10-x\)

For example lets take x= -5

Plug in -5 for x in \(10-x\)

\(10-(-5)\), negative times negative becomes positive

\(10+5=15\)

When the value of x is negative then the value of the expression becomes positive.
