Question

Solve the system of equations. If the system is dependent, express solutions in terms of the parameter z.x + y + z= 1x - y + 4z = -33x + y + z = 9

Answer 1

x + y + z = 1

x - y + 4z = -3

3x + y + z = 9

Three different equations with three unkown variables

The first we will do is to eliminate one of the variables
