fie x numarul;
dac ilsacdeem DE 10 ori, inseamna ca iil impartim la 10
atunci
x/10-100=100:10
x/10-100=10
x/10=110
x=1100
verificare x=1100
x/10=110
110-100=100:10
10=10
adevarat , bine rezolat

Scazut de 10 ori = impartire la 10
[tex] \frac{n}{10} -100= \frac{100}{10} n - 1000 = 100 n = 1000 + 100 n= 1100[/tex]
[tex] \frac{n}{10} -100= \frac{100}{10} n - 1000 = 100 n = 1000 + 100 n= 1100[/tex]
