Question

Which value of n makes the equation true? -1/2n = -8

A.) -16
B.) -4
C.) 4
D.) 16

Answer 1

D.) 16

Explanation:

Solve for n:

-n/2 = -8

Multiply both sides of -n/2 = -8 by -2:

(-2 (-n))/2 = -2 (-8)

-2×(-1)/2 = (-2 (-1))/2:

(-2 (-1))/2 n = -2 (-8)

(-2)/2 = (2 (-1))/2 = -1:

--1 n = -2 (-8)

(-1)^2 = 1:

n = -2 (-8)

-2 (-8) = 16:

Answer: n = 16

Answer 2

D

Explanation:

When we divide the entire equation by -1/2 to get rid of the coefficient of n we get n = 16.
