You can put this solution on YOUR website! For the given system, determine the best method (Graphing, Substitution, Addition) for solving.
3x - 2y = 8
x = -2y
Part B. Explain why you chose that method.
Substitution because the 2nd equation is all set up for substitution.
------
Part C. Solve the system. Give the final solution expressed as (x,y) point. (Showing your steps
---
Substitute for "x" and solve for "y":
3(-2y) - (2y) = 8
----
-6y-2y = 8
-8y = 8
y = -1
---
Solve for "x":
x = -2y
x = -2*-1 = 2
=====================
solution: (2,-1)
