                           Linear Systems: ELIMINATION METHOD 
                                       Guided Notes 
                                                
      Steps for solving systems using ELIMINATION. 
          STEP 1: Line up the x’s and y’s. 
          STEP 2: Look to see if one variable has opposite coefficients.  
               Yes, move to Step 3. 
               No, multiply one or both equations by a constant (LCM) in order to  
                        make the coefficients of the x or y terms opposites. 
          STEP 3: Add the equations together to eliminate one of the variables. 
          STEP 4: Solve for the remaining variable. 
          STEP 5: Substitute the value you found into one of the original equations to  
                         solve for the other variable. 
          STEP 6: Write your answer as an ordered pair. 
            
      Example 1: 
        STEP 1: Line up the x’s and y’s.        STEP 1:         2x+5y=17
        STEP 2: Look to see if one variable     STEP 2:         6x−5y=−9
         has opposite coefficients.               o  Yes 
          Yes, move to Step 3.                  STEP 3:             8x           =  8 
          No,                                    (y cancels)              8                8 
        STEP 3: Add the equations together      STEP 4:                    x =   1 
         to eliminate one of the variables.        
        STEP 4: Solve for the remaining         STEP 5:   2(1) + 5y = 17 
         variable.                                                 2  + 5y  = 17 
        STEP 5: Substitute the value you                       - 2               -2 
         found into one of the original                                    5y = 15 
         equations to solve for the other                                   5       5 
         variable.                                                          y = 3     
        STEP 6: Write your answer as an         STEP 6: (1, 3) 
         ordered pair.
