You have the equation -(x/4) = 5 and you want to find out what +x equals. To get rid of a negative fraction you need to multiply by the inverse. Our equation can be re-written like this
(-1/4)x = 5
and the negative inverse of the fraction is -4. Therefore, you must multiply both sides of the equal sign by -4:
(-4)(-1/4)x = (-4)(5)
x = -20.
Your answer is D, multiplication.
Hope this helps!
