a+=+1+%2B+b,.......1
b+=+5-2a...........2
---------------------------

a+=+1+%2B+b,.......1.substitute in 2
b+=+5-2%281+%2B+b%29...........2.....solve for b
b+=+5-2+-2b%29
b+%2B2b=+3

3b=+3
b=+1.....find a

a+=+1+%2B+b,.......1
a+=+1+%2B+1
a+=+2

check:
a+=+1+%2B+b,.......1
2+=+1+%2B+1,.......1
2+=+2,.......1

b+=+5-2a...........2
1+=+5-2%2A2...........2
1+=+5-4...........2
1=+1...........2
