Question

Chapter 3.5, Problem 29HP

To determine

To explain: The methodology to solve a system of four equations with four variables.

Expert Solution & Answer

Answer to Problem 29HP

Break the system into system of three equations and three variables and then solve.

Explanation of Solution

Given information:

The system of four equations.

Consider the system of four equations containing four variables.

In order to solve the system use the elimination and substitution to break the system the in system of three variables and three equation.

Take first and second, first and third and first and last equation together and solve them and eliminate one same variable in all three combinations.

Now, use elimination and substitution to compute the obtained system of three equations with three variables.
