You have to keep order of operations in mind.
1. Take care of the parentheses; distribute.
-3+6x-3=-20-8x
Simplified: 6x-6=-20-8x
2. Isolate the x variable.
Add 8x to both sides and add 6 to both sides.
14x=-14
3. Solve for x.
Divide by 14 on both sides.
x=-1
Answer:
The answer is 28/9
Step-by-step explanation:
Step one
Given information
We are given that the function is

And we are expected to find f(6), that is substitute the value of x with 6
Step two:

First do 6×8=48, then just add the 0's to the end to get 480,000
Y=4
How?
When they say directly you should multiply the x and y together. You would get -24, now using that number divide -24 by the new x(-6) you would get 4.
