**__Elimination__**
 * Solving systems of equations using elimination **


 * **Remember to look out for infinite solutions and no solutions**
 * **When you have two standard for equations you can use elimination to find solution**
 * **Add the two equations vertically to find the solution**

**__EXAMPLE 1__:**



**What do you do when they don’t eliminate themselves?** **You multiply either one or both equations by a number that will make one variable eliminate.**

__ **EXAMPLE 2:** __ **Here is a video showing you how to solve elimination problems:**

**Try these:** **1.)** **5x-6y=-32**  **3x+6y=48**

**2.)** **2x-5y=-22**  **10x-3y=22**

**3.)** **2x+18y=-9**  **4x+18y=-27**

**4.)** **5x+9y=112**  **3x-2y=8**
