 * Kalah Adams**
 * Main Idea: Solve an inequality with subtraction and addition, then graph.**


 * Problem #1**
 * x+4<5**


 * Solve x+4<5**
 * -4 -4**
 * x<1**

//__**GRANT BATZER - 6.1**__// //__**SOLVE INEQUALITIES USING ADDITION AND SUBTRACTION**__// //__**MAIN IDEAS:**__// **Solve the inequality by adding or subtracting numbers to a side of the inequality to get the variable for its self. Then, graph on a number line. if the inequality has a then when you graph it you use an open circle. If the inequality has a or ≥ then the circle with be a closed circle. adding the same number to each side of an inequality produces an equivalent inequality.** //__**EXAMPLE 1:**__// **x+4<5** __//**PROBLEM:2**//__ **r-4<-5** Solve and Graph
 * __//STEP ONE//:__ Subtract 4 from each side.**
 * x+4<5**
 * -4 -4**
 * __//STEP TWO//__: You are done with solving now you have to graph. Make a number line and graph the 1 with a open circle.**

 * Dan Beitzel 6.1**
 * Solve inequalities using addition and subtraction.**
 * using a number line. graphing of an inequality with one variable.**


 * example 1: X+4<5**
 * step one: subtract 4 from each side**
 * X+4<5**
 * -4 -4**
 * then make a number line with a a line and the circle is open.**
 * X<1**
 * __<---I-O I__**
 * 2 1 0**


 * example 2: 1__<__S-8**
 * Step 1: add 8 to each side**
 * +8 +8**
 * S__>__9**


 * __I b-I>__**
 * 10 9 8**
