Answer:
This system of equations has <em>no solution</em>. It is inconsistent.
Step-by-step explanation:
The last equation tells you z = -1.
Substituting this value for z in the other two equations allows them to be written as ...
-3x -y = 7
-3x -y = 3
There are no values of x and y that can make both these equations true.
Hi
ab - c =9
Solve for c
-c = 9 - ab
Divide both sides by -1
-c/-1 = 9-ab/-1
c = -9 + ab
Good luck !
