Solving Systems of Equations by Elimination – Part 2 1.) _____________ one or both equations by a constant that will create ___________________ coefficients for either x or y, if needed. 2.)_____________ the two equations, ______________________ one variable. 3.)_____________ for the remaining variable. 4.) _________________ your value into one of the original equations to find the ________________ value of x or y. Multiply opposite Add eliminating Solve Substitute remaining

Example x + 2y = 4 3x + 4y = 4

Elimination Practice Part 2

Socrative Summary #1 -4x – 15y = -17 -x + 5y = -13

Socrative Summary #2 5x + 2y = 20 10x + 4y = 60

Solving Systems of Equations by Elimination – Part 3 1.) _____________ one or both equations by a constant that will create ___________________ coefficients for either x or y, if needed. 2.)_____________ the two equations, ______________________ one variable. 3.)_____________ for the remaining variable. 4.) _________________ your value into one of the original equations to find the ________________ value of x or y. Multiply opposite Add eliminating Solve Substitute remaining

Example 2x + 3y = 10 3x + 4y = 18

Elimination Notes Part 3

Socrative Summary #1 -4x – 2y = x + 7y = -25

Socrative Summary #2 4x + 2y = x + 6y = -60
