Math Problem Statement
Answer this
Solution
The problem is asking for the solution to the system of equations represented by the graph and the given equations:
We are looking for the point where the two lines intersect, which represents the solution to the system of equations.
Solution by Substitution
We can solve the system algebraically by setting the two equations equal to each other since both are in the form :
Now, let's solve for :
-
Add to both sides:
-
Add to both sides:
-
Divide by 3:
Now substitute into either equation to find . Using :
Thus, the solution is .
Final Answer:
The correct solution is A. (3, -2), which matches the point of intersection in the graph.
