《gloomy》的歌詞如下：
歌曲原句：
If I saw you in the street today
How should I react, smile or frown?
Does your name make me wince in pain?
Am I trying hard to win again?
Got my make up on and took the stairs
Straight for your heart and pierced it like a pearl in your chest.
Did you hear my laugh? Is it funny yet?
Am I worth another chance? Or should I flee?
Verse 2:
So how should I feel today?
Lost, sad, happy or maybe scared?
Does your face show me I was right
To swerve every time I thought of you and die?
Chorus:
I'm so gloomy, broken inside.
And you could make me feel so much better, I could fly.
But every time you speak, my heart bleeds.
So what if it's the worst decision I've made?
Verse 3:
Should I hide my tears in darkened rooms?
From all the lights and candles they pour.
Could someone love me in the morning? Or just after midnight?
Are they best left burning for better things?
Chorus:
I'm so gloomy, broken inside.
And you could make me feel so much better, I could fly.
But every time you speak, my heart bleeds.
You won't let me, it won't let me rest. Oh oh oh. (3x)
Outro:
My skin crawls at the thought of your touch. Ohh no more.4 6/7減去一個未知數得到5 9/12。這個未知數是多少？問題：4 6/7減去一個未知數得到5 9/12。這個未知數是多少？
這個未知數為x，根據題目，可以得出方程：4 + 6/7 - x = 5 + 9/12。解方程得到未知數x的值為：$x = 5 + 9/12 - (4 + 6/7) = 5 + (18-4-6)/12 = 5 - 2/3 = 4 7/3$。所以，這個未知數是4 7/3。
