Answer:Therefore,The Correct option is C) -7Step-by-step explanation:Given:

………..Equation ( 1 )

………..Equation ( 2 )

To Find:

The Correct option for Eliminating “y”

Solution:

So to Eliminate “y” we need to add the equations after multiplying the second equation by

” – 7 ” (i.e option C) -7 )So Equation ( 2 ) becomeApplying Distributive Property we get

Now by adding +7y and -7y will get eliminate and we get

Therefore,The Correct option is C) -7
