b+c-b=2
Substitute b+c for a in the equation a-b=2.
b=-c+13 c=2
Solve the second equation for b and the third equation for c.
b=-2+13
Substitute 2 for c in the equation b=-c+13.
b=11
Calculate b from b=-2+13.
a=11+2
Substitute 11 for b and 2 for c in the equation a=b+c.
a=13
Calculate a from a=11+2.
a=13 b=11 c=2
The system is now solved.
