Which three variables can you eliminate?
Which three variables can you eliminate? In order to solve systems of equations in three variables, known as three-by-three systems, the primary goal is to eliminate one variable at a time to achieve back-substitution. A solution to a system of three equations in three variables (x,y,z), ( x , y , z ) , is called an ordered triple. Can 2 equations solve 3 variables? It is simply impossible to have 3 basic variables - a maximum of 2 are allowed. So, assuming we have a 2 basic variables, we have 1 free variable. The equation can be solved, but...
