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.


A quick demonstration of how to interpret a line graph of a compound inequality and write its algebraic form.


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


Shows how to factor the greatest common factor from a simple linear binomial


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…
