a - b = 33 <=> 3 segmente = 33 => un segment = 11 = c => b=3c = 33 => a= 2b = 66
Mai intai notezi numerele cu: x-primul numar; y-al doilea numar ; z-al treilea numar.
x=2*3z=>x=6z
x=2y
x-y=33
x=6z si x=2y =>6z=2y /:2 =>3z=y => y=3z
Pe y il inlocuim cu [tex] \frac{1}{2} x[/tex] => x-[tex] \frac{1}{2} x[/tex]=33=.2x-x=66=>x=66
x=2y => 66=2y /:2=> y=33
x=6z=> 66=6z /:6=> z=11
x=2*3z=>x=6z
x=2y
x-y=33
x=6z si x=2y =>6z=2y /:2 =>3z=y => y=3z
Pe y il inlocuim cu [tex] \frac{1}{2} x[/tex] => x-[tex] \frac{1}{2} x[/tex]=33=.2x-x=66=>x=66
x=2y => 66=2y /:2=> y=33
x=6z=> 66=6z /:6=> z=11
