-3k=1+2
Consider the first equation. Add 2 to both sides.
-3k=3
Add 1 and 2 to get 3.
k=\frac{3}{-3}
Divide both sides by -3.
k=-1
Divide 3 by -3 to get -1.
l=-1
Consider the second equation. Insert the known values of variables into the equation.
m=-1
Consider the third equation. Insert the known values of variables into the equation.
k=-1 l=-1 m=-1
The system is now solved.
