Question

Solve -16x = -80. A. -64, B. -5, C. -96, D. 5

Answer 1

B. -5

Explanation:

-16x = -80

Divide both sides by -16, so that the x stands alone

(-16x) / (-16) = (-80) / (-16)

The two -16's cancel each other out on the left side

x = 80 / -16

So now all we have is 80 divided by -16, which we can simplify to

x = -5

Answer 2

-16x= -80

x has to be a positive number in order to be multiplied by a negative number and still get a negative answer. Therefore D is the only correct option.
