Use Kramer’s Rule to solve for x, y, and z from the following equations:

4x-7y+2z=4,

3x-11y+5z=3,

-9x+4y+3z=1.

(Hint: Use Determinants)

Expert Solution

Crammers Rule:

, , ,

1) Unique solution exists.

2) Infinite solutions exists.

3) No solution exists.

Solution is : , ,

Using this method now we will find the solution of the given problem.

As

4x-7y+2z=4,

3x-11y+5z=3,

-9x+4y+3z=1

Now we will calculate D, D₁, D₂ and D₃

As Given problem has a unique solution

, ,

Thus final Solution :
