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
Answer:
A
Step-by-step explanation:
Both are ten numbers apart

Answer:


Solve for x:
Begin isolating the variable by adding "c" to both sides:


Divide both sides by a/b, or multiply by the reciprocal (b/a)

Therefore:
