Graph and check: "graph the linear system and estimate the solution. Then check the solution algebraically.

Step 1. Graph the linear system of equations

Step 2. Based on the above graph, the intersection point is (3,-1).

Step 3. Check if (3,-1) or x=3 and y=-1 satisfies the system of equaitons

Given , then which is a true statment.
Given , then which is a true statement.

Step 4. ANSWER: The solution sis (3,-1) or x=3 and y=-1.

I hope the above steps and explanation were helpful.
