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.
