11=2-x
Consider the second equation. Add 4 and 7 to get 11.
2-x=11
Swap sides so that all variable terms are on the left hand side.
-x=11-2
Subtract 2 from both sides.
-x=9
Subtract 2 from 11 to get 9.
x=-9
Divide both sides by -1.
n-9=7
Consider the first equation. Insert the known values of variables into the equation.
n=7+9
Add 9 to both sides.
n=16
Add 7 and 9 to get 16.
n=16 x=-9
The system is now solved.
