Question

Solve the system of equations.
2x-5y-2z= -2
6x-15y-6z=20
2x-2y-5z = 4

Answer 1

No solution

Explanation:

2x-5y-2z= -2

6x-15y-6z=20

2x-2y-5z = 4

3rd eq - 1st eq

3y - 3z = 6

2nd eq - 3 × 1st eq

0 = 26

This is a false statement. Therefore, there is no solution.

Answer: No solution
