Bell Ringer 2x – 3y = 4 5x + 3y = 10

2
HW Check Check elimination part 1 practice

3
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

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

5
Elimination Practice Part 2

6
Socrative Summary #1 -4x – 15y = -17 -x + 5y = -13

7
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

9
Example 2x + 3y = 10 3x + 4y = 18
