Answer:
y = 4
Step-by-step explanation:
Step 1: Write equation
9/4y - 12 = 1/4y - 4
Step 2: Solve for <em>y</em>
- Subtract 1/4y on both sides: 8/4y - 12 = -4
- Simplify: 2y - 12 = -4
- Add 12 to both sides: 2y = 8
- Divide both sides by 2: y = 4
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
9/4(4) - 12 = 1/4(4) - 4
9 - 12 = 1 - 4
-3 = -3
Answer: ![f^{-1}(x)=2x-6](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28x%29%3D2x-6)
Step-by-step explanation:
To find the inverse, we want to switch the y with x and x with y. Once we do that, we solve for y.
[switch x and y]
[subtract both sides by 3]
[multiply both sides by 2]
![y=2x-6](https://tex.z-dn.net/?f=y%3D2x-6)
Now, we know that

Answer:
-1
Step-by-step explanation:
– 7x – 5 = x + 3
-7x-x=3+5
-8x=8
x=8/-8
x=-1
