c=-3 9a+3b+c=0 a-b+c=0
Reorder the equations.
9a+3b-3=0 a-b-3=0
Substitute -3 for c in the second and third equation.
b=1-3a a=b+3
Solve these equations for b and a respectively.
a=1-3a+3
Substitute 1-3a for b in the equation a=b+3.
a=1
Solve a=1-3a+3 for a.
b=1-3
Substitute 1 for a in the equation b=1-3a.
b=-2
Calculate b from b=1-3.
a=1 b=-2 c=-3
The system is now solved.
