The computer salesman would have to sell 12 computers.
I'm going to assume you meant 27 because three odd integers added together can't be even.
The three integers are expressed as x, y and z:
x+y+z=27
x+2=y
y+2=z
x+4=z
x+x+2+x+4=27
x+x+x+2+4=27
3x+6=27
3x=21
x=7
y=9
z=11
7+9+11=27
The numbers are 7, 9 and 11
Hope this helps.
13x = 39 can replace 3x + 5y = 59 in the original system and still produce the same solution.
