The equation (1) is divided by 2 to create new equivalent system of equations.
Step-by-step explanation:
The given systems of equations are:

Considering 8y instead of 8 in eq(1)
We need to identify what action was completed to create this new equivalent system of equations? 
Comparing given equations we came to know that equation(1) is divided by 2 to get the new equation i.e

While second equation is same as given.
So, The equation (1) is divided by 2 to create new equivalent system of equations.

Answer:
1 kilometer
0.621371 miles
Step-by-step explanation:
Given data
In the given table we are presented with the conversion table for common units and we are required to present the conversion for kilometers to miles
Hence the conversion from kilometers to miles is presented below
1 kilometer
0.621371 mile
6.3 x 10'-8
63 - 8
55
55 is the answer
In order to solve this we need to get x by itself on one side.
We need o start by adding across the 4 so that we get:
x/3 = -7 + 4 = -3
We then need to multiply both sides by 3 to get a singular x:
x = -3 * 3 = -9
