Answer:
n=-22
Step-by-step explanation:
rewrite the equation as <u>5(n+4)</u><u> </u>= n-8
3
now distribute the 5 through the parentheses <u>5n</u><u>+</u><u>2</u><u>0</u><u> </u>= n-8
3
multiply each side by 3 5n+20=3n - 24
subrtact 3n from both sides 5n+20=3n - 24
-3n -3n
2n+20=-24
then subtract 20 from each side 2n +20=-24
-20 -20
Giving you 2n=-44 then divide both sides by 2
<u>2n</u>=<u>-44</u><u> </u>Giving you n=-22
2 2
