Question

What are the solution to the system equations

Answer 1

x=-4, y=7. (-4, 7).

Explanation:

-7x-2y=14

6x+6y=18

----------------

simplify 6x+6y=18 into x+y=3,

-7x-2y=14

x+y=3

--------------

-7x-2y=14

7(x+y)=7(3)

-----------------

-7x-2y=14

7x+7y=21

---------------

5y=35

y=35/5

y=7

x+7=3

x=3-7

x=-4
