x + y = 4(1 + y) + y = 4 1 + 2y = 4 1 - 1 + 2y = 4 2y = 4 y = 2
-x = -1 + y-x = -1 +2
-x = 1
.... that's as far I can go... sorry

Answer:
The value of y is 21.
Step-by-step explanation:
The formula of inversely proportional is y = k/x where k is a constant. So in order to find y, you first have to find the value of k by substituing x and y values into the formula :
![y = \frac{k}{x}](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7Bk%7D%7Bx%7D%20)
Let y = -105,
Let x = -3,
![- 105 = \frac{k}{ - 3}](https://tex.z-dn.net/?f=%20-%20105%20%3D%20%20%5Cfrac%7Bk%7D%7B%20-%203%7D%20)
![k = - 105 \times - 3](https://tex.z-dn.net/?f=k%20%3D%20%20-%20105%20%5Ctimes%20%20-%203)
![k = 315](https://tex.z-dn.net/?f=k%20%3D%20315)
We have already found k value. Next you have to find the value of y :
![y = \frac{315}{x}](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B315%7D%7Bx%7D%20)
Let x = 15,
![y = \frac{315}{15}](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B315%7D%7B15%7D%20)
![y = 21](https://tex.z-dn.net/?f=y%20%3D%2021)
Answer:
√3 x^5y
First, let's do √3
√3=1.7
1.7 • x^5 • y
if you want
1.7 • X^4• x• y.
There are tons of equivalent's!
