Answer: 5 = 1
Step-by-step explanation: if you divide by negative 5 you would get what i got above. It's not a solution. But I am not sure I understand what you are asking. Are these ratios? It would make sense if they were because 25 : 5 simplified equals 5:1
U = 5
This is because you divide both sides by -5. -25/-5 = 5 because they are both negative, so U = {5}
