Answer:
D)x = 4∕3y – 4
Step-by-step explanation:
![\frac{x}{4} + \frac{y}{3} = 1](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B4%7D%20%20%2B%20%20%5Cfrac%7By%7D%7B3%7D%20%20%3D%201)
![3x + 4y = 12](https://tex.z-dn.net/?f=3x%20%2B%204y%20%3D%2012)
![3x = 12 - 4y](https://tex.z-dn.net/?f=3x%20%3D%2012%20-%204y)
![x = 4 - \frac{4}{3} y](https://tex.z-dn.net/?f=x%20%3D%204%20-%20%20%5Cfrac%7B4%7D%7B3%7D%20y)
![x = 4 - \frac{4}{3} y](https://tex.z-dn.net/?f=x%20%3D%204%20-%20%20%5Cfrac%7B4%7D%7B3%7D%20y)
Answer:first one is dependent
second one is independent

I do exercises on it
Answer:
x=80
Step-by-step explanation:
The angle of a line is 180*.
The equation would be (x+20)+x=180
Subtract 20 from both sides: 2x=160
Divide by 2: x=80
That's your answer!
I hope this helps!
