GRAPHING METHOD

 

 

STEP 1: Graph both solutions.
STEP 2: From looking at the graph              the lines should appear to              interstect at a point.
STEP 3: You can check the solution              algebraically.
  
1 = -2(1)+ 3                1 = -(1) + 2     1 = 1                          1 = 1

* The solution is (1, 1).
