Solve two-step linear equations and inequalities in one variable over the rational numbers, interpret the solution or solutions in the context from which they arose, and verify the reasonableness of the results.

Student Friendly Language

           This means you are able to solve equations with more than one step and be able to explain why you did what you did. You also have to be able to define rational numbers and inequalities and know how to use them.

Here's an example problem to show you how to do two step equations.

 Solve for y

3(9x y)-2=16

Step 1.  First, you do the work in the parenthesis,9x y

3x9y-2=16

Step 2. Next, you must get y by it self so we add 2 to each side.                         

3x9y-2=16

                                                       +2   +2  

                 Step 3.    Now, to get 3 by it self, we must divide each side by 3 or multiply both sides by ⅓

3/3 x9y= 18/3

                                   Step 4.  Now we have to divide each side by 9, to isolate y

                                               9/9y=6/9

                                                       Final product

                                        y=2/3
