This demo discusses how to set up two equations to solve the situation described, and then choose the best method to use to solve for each of the variables.
|
|
|
This talks about why we need two equations to solve for two unknown values, and then demonstrates how to add two equations together to eliminate one varaible and solve for the other one, then find…

|
This shows how to transform all given equation that are not in slope-intercept form and then pick out the slopes of all three given lines and compare them to see if they are parallel, perpendicular…
|
|
|
This shows the method of using the point-slope form to write the equation, then solving that form for y to get y = mx + b.

|
|
This describes how to solve each side of a compound inequality, then using the graphs of each part determine the interval notation for the entire compound statement.
|
|
|
Presents a compound inequality where both sides have to be solved for the variable first, and then shows how to graph the simplified results
|
|
|
This contains one example of solving an inequality as described in the title.
|
|
|
Shows one example of solving a iinear inequality in two steps.
|
|
|
This states the Multiplicative Propery of Inequality, then demonstates how it works with two examples.
|
|
|
A demo that only shows a one step process of adding an integer to both sides of an inequality so that the variable stands alone and we can tell what values are true for that inequality.

|
|
This describes the process of solving for a particular variable in terms of other variables in an equation. There is a need to go further to combine like terms before it is complete.
|
|
|
This demonstrates two ways of dealing with a literal equation that has parentheses which adds an extra step in the process in the first method, bu t not the second.
|
|
|
A somewhat fancierversion of seveal solving equation versions that should help solidify the process in your mind.
|
|
|
A more complicated version of solving an equation. It specifically addresses dealing with two variable terms on the same side of the equals sigh.
|
|
|
A simpler version of an equation that needs distribution across a set of parenthese as the first step to solving for the variable
|
|
|
A short and simple demo about adding like variable terns that are together on one side of the equals sign in an equation.
