-9=c -5=4a+2b+c -8=a-b+c
Reorder the equations.
c=-9
Solve -9=c for c.
-5=4a+2b-9 -8=a-b-9
Substitute -9 for c in the second and third equation.
b=2-2a a=b+1
Solve these equations for b and a respectively.
a=2-2a+1
Substitute 2-2a for b in the equation a=b+1.
a=1
Solve a=2-2a+1 for a.
b=2-2
Substitute 1 for a in the equation b=2-2a.
b=0
Calculate b from b=2-2.
a=1 b=0 c=-9
The system is now solved.
