Hi there!
We want to make x the subject of the formula, which means to solve the formula for x
Here is the given formula:
y=7x-1
Our ultimate goal is to isolate x onto one side
Start by subtracting 7x from both sides
y-7x=-1
Subtract y from both sides to remove it from the left side
-7x=-y-1
Divide both sides by 7
x=
Simplify (factor -1 out of the numerator and denominator, then cancel it out)
x=
x=
Hope this helps!

Answer: 
Explanation:
The simplification of that expression is done in this way:
1) The negative sign is placed in front of the whole fraction
2) 27 is divided by 3 resulting in 9: 27 / 3 = 9
3) x^2 on the numerator cancels out with x^2 of the denominator
4) z on the numerator is cancelled out with 1 z of the denominator and the result is z^5 in the denominatoir.
All that yields to :
9
- --------
z^5
