Hey there!!

w(x) = -2x + 7

x = -3

Now, we plug in the value of -3 instead of x

...w(-3) = -2(-3) + 7

...w(-3) = 6+7

...w(-3) = 13

Hence, the required answer is 13

Hope my answer helps!!

W(x) = -2x + 7

W(3) = -2(-3) + 7         this is when x = -3

        = 6 + 7

       =    13

***********************************************

If you meant to type in: W(x) = -3 then

-3 = -2x + 7

-10 = -2x

[tex]\frac{-10}{-2} = \frac{-2x}{-2}[/tex]

 5  = x
