3. Glance back: Think, Pair, Share Which of the following BR questions were “eliminated”? How can you tell? 1)4x + (-7x) = -3x 2)-6y + 6y = 0 3)-5 – (-5) = 0 4)8 – (-8) = 16

4. Solving Systems of Equations by Elimination – Part 1 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
