Answer:
n = negative quarter.
Step-by-step explanation:

Be aware that when ever you pelt something across, you change the sign that is behind it. If it don't have a sign that means its a + already so if you pelt it across the equal sign, it will become -... lets begin...
40n = -18 + 16 - 8
40n = -10
n = -10/40
n = -1/4
