3-2 Solving Systems of Equations Algebraically Algebra II CP
Vocabulary • Substitution Method • Elimination Method
Ex 17: • Solve the system of equations by substitution x + 2y = 8 ½ x – y = 18
Ex : • Solve the system of equations by elimination 2x + y = 4 3x + y = 8
Ex : • Solve the system of equations by elimination 2x + 3y = 12 5x – 2y = 11
Ex last one: • Use either method to solve the system of equations 2x = 7 + y 6x – 3y = 24
