1. Elimination Method Day 2 Today’s Objective: I can solve a system using elimination

2. 2x – 3y = 5 x – 2y = 4 y = -3 Step 2 Step 3 y = -3 x – 2y = 4 x – 2( ) = 4 x + 6 = 4 x = -2 Step 4 Step 5 (-2, -3) -3 2x – 3y = 5 -2( ) -2x + 4y = -8

3. 2x + 3y = 10 3x – 4y = -2 17x = 34 Step 2 Step 3 x = 2 2x + 3y = 10 2( ) + 3y = 10 4 + 3y = 10 3y = 6 y = 2 Step 4 Step 5 (2, 2) 2 8x + 12y = 40 3( ) 4( ) 9x – 12y = -6

4. 3x + 2y = 17 2x + 5y = 26 -11y = -44 Step 2 Step 3 y = 4 3x + 2y = 17 3x + 2( ) = 17 3x + 8 = 17 3x = 9 x = 3 Step 4 Step 5 (3, 4) 4 6x + 4y = 34 -3( ) 2( ) -6x – 15y = -78
