x+x+2+x+4+x+6+x+8 = x+1+x+3+x+5+21
5x+20 = 3x+30
2x = 10
x = 5 this is the smallest integer
---------------------------
Check:
5+7+9+11+13 = 6+8+10+21
45 = 45 Correct

x-4 x-2 x x+2 x+4 five con odd integers.

x-4 and x-2 are the smallest
(x-4)+(x-2)=(x)+(x+2)+(x+4) -21
2x-6=3x-15
x=9
the numbers are 5 7 9 11 13
the smallest is 5
