-4 | 8-5n | =13
-4 l 8 - 5n l = 13 divide both sides by -4
l 8 - 5n l = -13 / 4
This has no solutions because the result of an absolute value can never be negative
Wait this wont even work because negitive*positive is always negitive! Also an absolute value can never be negitive or it is not an absolute value! like what he said. So the answer is Not posible!
