ASAP- Recall that variables represent changing values. In this unit, you will work with equations that contain two different variables. What types of situations might be modeled with equations containing two or more variables? If the value of one variable changes, must the value of the other variable change for the equation to remain true? How would the number of solutions for an equation with two variables differ from the number of solutions for an equation with only one? Explain.
