Two-step inequalities

The topic  appears under the 7th Grade Math Mission. This exercise practice two-step inequalities.

Types of Problems
There are two types of problems in this exercise:


 * 1) Solve the inequality: This problem provides a linear equality that requires an addition step and a division step. The student is asked to isolate the variable and use the drop-down menu and textbox to provide the solution.T-si1.png
 * 2) Select the correct graph: This problem provides a linear inequality that requires two steps to solve. After solving the inequality, the student is asked to select the graph that is draw correctly to represent the inequality.T-si2.png

Strategies
The Properties of Inequality are necessary to ensure doing this exercise correctly.
 * 1) The Properties of Inequality are almost the same as the properties of equality, except when multiplying or dividing by a negative the inequality sign will flip.
 * 2) The graph problems can also be completed by choosing a good test number or two and plugging them into the inequalities.
