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 demo takes some thought so you may want to watch it a few times to fully understand. Writing the expression and then we simplify it so that it is more usable in future.


This shows how to represent the two unknowns using their given relationship so that a linear equation can be written using one variable. Then that equation is solved to answer the question


A quick statement of the property followed by two examples of its use.


This demonstrates how to write the function that includes the initial amount multiplied by the percent remaining or the initial amount multiplied by one plus the percent increase, with either being…


This describes what to look for when simplifying radicals.


A second look at factoring the top and bottom of a fraction in algebra that then reduces that fraction.


This type of equation is solved by factoring a GCF from both terms once the proper form is achieved. Then the zero product property allows the separation of the two factors into two solvable linear…


One of the simpler factoring techniques if you know what you are looking for.


Talks about how to interpret the words to create two equations, then solves them together using the elimination method, making opposites of one variable's terms sot that the equations can be…


Shows how to organize the information given in words using a chart. This allows you to use the percent formula to show how the columns are combined to then find an equation to solve for the answer,


Finding the amount from taking a percentage off or adding a percentage on, then finding the new amount.


Describes an algebraic method for finding what you need for your next score to achieve a certain average or mean.


An introduction to distance, rate, and time problems where a chart is helpful to organize the information.


A simple word problem to get us started with "distance equals rate (or speed) times time.


The beginnings of understanding how to solve equations by doing something to both sides, keeping it equal
