b=4 a=3c a+b=c
Reorder the equations.
a+4=c
Substitute 4 for b in the equation a+b=c.
c=a+4
Solve a+4=c for c.
c=3c+4
Substitute 3c for a in the equation c=a+4.
c=-2
Solve c=3c+4 for c.
a=3\left(-2\right)
Substitute -2 for c in the equation a=3c.
a=-6
Calculate a from a=3\left(-2\right).
a=-6 b=4 c=-2
The system is now solved.
