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.

Step-by-step explanation:

- <em><u>distribute</u></em><em><u> </u></em>4 through the parentheses


- move the <em><u>variable</u></em><u> </u>to the left hand side and change its sign

- move the <em><u>constant </u></em>to the right hand side and change its sign

- collect<em><u> like</u></em><em><u> terms</u></em>
<em><u>
</u></em>

- divide both sides of the equation by <em>-</em><em>5</em>
