So this is what I got:
(b+9)+b+c=82
that means that
c= 82-((b+9)+b)
putting it all together we have
(b+9)+b+82-((b+9)+b)= 82
(b+9)+b+c=82
that means that
c= 82-((b+9)+b)
putting it all together we have
(b+9)+b+82-((b+9)+b)= 82

first number ---- x
second number --- x+9
third number ----- 82 - x - x - 9
= 72 -2x
all three numbers are expressed in terms of one variable:
x , x+9, and 72-2x
second number --- x+9
third number ----- 82 - x - x - 9
= 72 -2x
all three numbers are expressed in terms of one variable:
x , x+9, and 72-2x
