Answer 2

Answer:

To use elimination to solve a system of three equations with three variables, follow this procedure:

Graphical methods seek to reveal patterns that are indicative of problems with either the model or the data, and often are useful in suggesting ways to improve the data analysis, for example, by transformation of the variables or other respecification of the model.

The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other.
