Question

Use technology to solve the system of equations. Express all solutions as decimals, rounded to one decimal place.

2.1x + 0.7y - 1.4z = -2.5
3.5x - 4.2y - 4.92 = 4.0
1.1x + 2.2y - 3.3z = -9.1
(x, y, z) =

Answer 1

To solve the given system of equations, use a graphing calculator or computer algebra system (CAS) to input the equations and solve for x, y, and z. The solution is (x, y, z) = (1.3, -0.7, 1.5).

Step-by-step explanation:

To solve the given system of equations using technology, we can use a graphing calculator or a computer algebra system (CAS). One option is to use the substitution method. Here are the steps:

1. Input the equations into your calculator or CAS.
2. Choose the option to solve the system of equations.
3. Round the solutions to one decimal place.
4. The solution to the system of equations is (x, y, z) = (1.3, -0.7, 1.5).
