2.6B Systems Elimination.notebook October 18, 2018 Warm State the property or identity. 1) 27 + 0 = 27 2) a + 4 = 11 4 4 a = 15 I can solve systems of equations by elimination. 3.) What is the first step in solving a system of equations using substitution method? Let's think about... x + y = 5 x y = 1 Yipee! It's "systems of equations"! your teacher...lo Is (14, 5) a solution for x + 14y = 84 2x 7y = 7 ?? Solving by elimination: 2x 2y = 8 2x + 2y = 4 4x + 3y = 16 2x 3y = 8 2x 3y = 4 4x + 5y = 8 5x 3y = 16 4x + 5y = 2
