Unit 8: Systems of Equations6.2 Solving Systems using Substitution

Date

Substitution Another method for solving a system of equations (ie, see where lines intersect)

Step 1: Solve an equation for x or y, if necessary(Get a sticky note by itself.)

Step 2: Substitute your answer from #1 into the other equation. Solve for the other variable.(Substitute into the other sticky note of the same color.)

Step 3: Use your value from #2 to find the last missing variable.(Find the different sticky note variable.)
