Option: D is the correct answer.

D.Multiply each side by −5, add 25 to each side

Step-by-step explanation:

We are given an algebraic expression in terms of variable x as follows:

$\dfrac{-1}{5}(x-25)=7$

Now, firstly we will multiply both side of the equation by -5 to get:

$\dfrac{-1}{5}\times (-5)(x-25)=7\times -5\\\\i.e.\\\\x-25=-35$

Now we add both side of the equation by 25 to get:

$x-25+25=-35+25\\\\i.e.\\\\x+0=-10\\\\i.e.\\\\x=-10$
