Chapter A1, Problem 57PE

For Exercises 49-58, solve the system by using Cramer’s rule, if possible. Otherwise, use another method. If a system does not have a unique solution, determine the number of solutions and whether the system is inconsistent or the equations are dependent. (See Example 8.)

57. x + y + 8 z = 3 2 x + y + 11 z = 4 x + 3 z = 0

Example 8

Analyzing a Dependent System of Equations Solve the system by using Cramer’s rule if possible. 2 x 3 y = 6 6 x + 9 y = 18
