Answer:
y = 20 x = 6
Step-by-step explanation:
1 (3x+ 2y = 58 ------------> -3x + -2y = -58
1x + 2y = 46 --------------> 1x + 2y = 46
____________
-2x = -12
-----------------
-2x -2x
x = 6
3(6) + 2y = 58
18 + 2y = 58
-18 -18
------------------
2y = 40
----- -----
2y 2y
y = 20
Let's solve for f.
y=f−1x
Step 1: Flip the equation.
f−x=y
Step 2: Add x to both sides.
f−x+x=y+x
f=x+y
Answer:
f=x+y

Answer:
x ≈ 18.7
Step-by-step explanation:
This is a big equation, so let's break it down a bit.
![\frac{3}{2} \sqrt[4]{(2(x-6) ^3 )} +4=16](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D%20%5Csqrt%5B4%5D%7B%282%28x-6%29%20%5E3%20%29%7D%20%2B4%3D16)
Let's start by isolating the radical which is x.
So subtract 4 from both sides :
![\frac{3}{2} \sqrt[4]{(2(x-6) ^3)}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D%20%5Csqrt%5B4%5D%7B%282%28x-6%29%20%5E3%29%7D)

Now multiply both sides by 2 to get rid of the fraction :
![3\sqrt[4]{(2(x-6)^3)} = 24](https://tex.z-dn.net/?f=3%5Csqrt%5B4%5D%7B%282%28x-6%29%5E3%29%7D%20%3D%2024)
Now divide both sides by 3 to get rid of the number out of the poly root :
![\sqrt[4]{2(x-6) ^3}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B2%28x-6%29%20%5E3%7D)

Now take both sides of the equation to the power of 4 :

And lastly, solve :
