Systems of Equations Review: Substitution Linear Combination 2 Methods to Solve:

Example of Substitution: Solve the following system of equations: y = 4x – 2 2x – 3y = -4

Example of Substitution: Solve the following system of equations: x = -2y + 4 x – 3y = -11

Example of Substitution: Solve the following system of equations: 2x + y = 0 y – x = 6

Example of Linear Combination: Solve the following system of equations: 2x – y = -2 3x + y = -13

Example of Linear Combination: Solve the following system of equations: 4x – 2y = -12 5x + y = 6

Example of Linear Combination: Solve the following system of equations: 3x – 2y = -17 2x + 3y = -7
