Answer:
x = 15
Step-by-step explanation:
We want to solve for x in 3*(2x + 5) = 3x + 4x
First simplify.
3*(2x + 5) = 7x
Next, distribute the 3.
3*2x + 3*5 = 7x
6x + 15 = 7x
15 = 7x - 6x
15 = x
Answer:
![f^{-1}(x)=\dfrac{2x+6}{5-x}](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3D%5Cdfrac%7B2x%2B6%7D%7B5-x%7D)
Step-by-step explanation:
Swap x and y, then solve for y.
![x=\dfrac{5y-6}{y+2}\\\\x(y+2)=5y-6\\\\xy+2x=5y-6\\\\2x+6=5y-xy\\\\y=\dfrac{2x+6}{5-x}\\\\f^{-1}(x)=\dfrac{2x+6}{5-x}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B5y-6%7D%7By%2B2%7D%5C%5C%5C%5Cx%28y%2B2%29%3D5y-6%5C%5C%5C%5Cxy%2B2x%3D5y-6%5C%5C%5C%5C2x%2B6%3D5y-xy%5C%5C%5C%5Cy%3D%5Cdfrac%7B2x%2B6%7D%7B5-x%7D%5C%5C%5C%5Cf%5E%7B-1%7D%28x%29%3D%5Cdfrac%7B2x%2B6%7D%7B5-x%7D)
