You have to get r by itself on one side. Multiply both sides by 238 to cancel it out of the denominator on the left side.
You are left with r = 8 × 238 or r = 1904.
To check, plug 1904 back into the equation.
1904 ÷ 238 = 8
8 = 8 (True)

Answer:
a. ![y=\frac{2x}{x-5}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B2x%7D%7Bx-5%7D)
b. ![y=\frac{2-4x}{x-3}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B2-4x%7D%7Bx-3%7D)
Step-by-step explanation:
change switch x and y and then solve for y.
a. ![x=\frac{5y}{y-2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B5y%7D%7By-2%7D)
![x(y-2)=5y](https://tex.z-dn.net/?f=x%28y-2%29%3D5y)
![xy-2x=5y](https://tex.z-dn.net/?f=xy-2x%3D5y)
![xy-5y=2x](https://tex.z-dn.net/?f=xy-5y%3D2x)
![y(x-5)=2x](https://tex.z-dn.net/?f=y%28x-5%29%3D2x)
![y=\frac{2x}{x-5}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B2x%7D%7Bx-5%7D)
same for b.
b. ![x=\frac{3y+2}{y+4}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B3y%2B2%7D%7By%2B4%7D)
![x(y+4)=3y+2](https://tex.z-dn.net/?f=x%28y%2B4%29%3D3y%2B2)
![xy+4x=3y+2](https://tex.z-dn.net/?f=xy%2B4x%3D3y%2B2)
![xy-3y=2-4x](https://tex.z-dn.net/?f=xy-3y%3D2-4x)
![y(x-3)=2-4x](https://tex.z-dn.net/?f=y%28x-3%29%3D2-4x)
![y=\frac{2-4x}{x-3}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B2-4x%7D%7Bx-3%7D)
Answer:
Step-by-step explanation:
First, factor the (3y-4) and group the remaining terms
y²(3y-4) +7 (3y-4)
(y²+7)(3y-4)
I hope this helps (:
