Try solving each of the following systems using matrices on your graphing calculator. Click "Check Your Answer" to see the solution for each problem..

**Practice 1:** Find the solution to the system

**Practice 2:** Find the solution to the system of equations

6*x* - 9*y* - 8*z* = 3

4*x* + 7*y* + 2*z* = -7

3*x* + 5*y* - 9*z* = 26

**Practice 3:** Find the solution to the system of equations

*x* + 4*y* - *z* = 1

*x* + *y* + *z* = 0

2*x* + 3*z* = 0

**Practice 4:** Find the solution to the system of equations

6*x* - 2*y* + 2*z* = 14

*x* - 2*y* + 5*z* = 1

3*x* - *y* + *z* = 5
