n=7\left(-3\right)+1
Consider the second equation. Insert the known values of variables into the equation.
n=-21+1
Multiply 7 and -3 to get -21.
n=-20
Add -21 and 1 to get -20.
o=-20
Consider the third equation. Insert the known values of variables into the equation.
m=-3 n=-20 o=-20
The system is now solved.
