Answer 2

Answer:

The value of expression $-x+2$ at $x=-1$ is $3$.    

Step-by-step explanation:

Given : The expression is $-x+2$.

To find : The value of given expression $-x+2$ when $x=-1$.

Solution :

• The given expression is $-x+2$.
• We have to find the value of given expression when $x=-1$.
• To find the value of expression, put $x=-1$ in the given expression.
• The expression is,

       $-x+2=-(-1)+2$

                 = $1+2$   (∵ -ve*-ve=+ve)

                 = $3$

• ∴ The value of expression $-x+2$ at $x=-1$ is $3$.
