c=12 b=a-c a=7b
Reorder the equations.
b=a-12
Substitute 12 for c in the equation b=a-c.
a=7\left(a-12\right)
Substitute a-12 for b in the equation a=7b.
a=14
Solve a=7\left(a-12\right) for a.
b=14-12
Substitute 14 for a in the equation b=a-12.
b=2
Calculate b from b=14-12.
a=14 b=2 c=12
The system is now solved.
