The Correct answer is
(n)(4) = (7)(8)
4n = 56
n = 14
100%-30%=70%
100%+30%=130%
to decrese by 30%, multiply by 70%
to increase by 30%, multiply by 130%
You would subtract 15 on both sides and then you would have 2x=-14 then you divide both sides by 2 and x would equal -7
The transformed equation is:

Step-by-step explanation:
We have to convert the equation in the form

Given equation is:

Adding 8 on both sides

In the given equation
a = x
b= ?
So,

So 3^2 will be added on both sides

Hence,
The transformed equation is:
