a=-b+2
Solve a+b=2 for a.
-b+2-b=4
Substitute -b+2 for a in the equation a-b=4.
c=-b+3 b=-1
Solve the second equation for c and the third equation for b.
c=-\left(-1\right)+3
Substitute -1 for b in the equation c=-b+3.
c=4
Calculate c from c=-\left(-1\right)+3.
a=-\left(-1\right)+2
Substitute -1 for b in the equation a=-b+2.
a=3
Calculate a from a=-\left(-1\right)+2.
a=3 b=-1 c=4
The system is now solved.
