Answer:

n = +/- 6

Explanation:

First, move the non variable to the right side,

-1/2 n^2 = -18

then multiply each side by the reciprocal of the fraction to cancel the fraction,

-2*(-1/2 n^2) = -2*(-18) --> n^2 = 36

then take the square root of both sides.

n = +/- 6

Also, the answer is +/- because when we take the square root of 36, both 6 and -6 squared can equal 36, so both need to be consider as the answer.
