Answer: They were not correct it was bigger by 2.5 so the people were wrong
Answer:
Part 1) The solution of the system of equations is (2,-5)
Part 2) The solution of the system of equations is (2,4)
Step-by-step explanation:
Part 1) Linear combination
we have
-----> equation A
-----> equation B
Multiply equation B by 2 both sides

-----> equation C
Adds equation A and equation C

Find the value of y




The solution of the system of equations is (2,-5)
Part 2) By graph
-----> equation A
-----> equation B
we know that
The solution of the system of equations is the intersection point both graphs
Using a graphing tool
The intersection point is (2,4)
therefore
The solution of the system of equations is the point (2,4)
see the attached figure
