Răspuns :
a+b=119
a:b=3 rest 19
a=3b+19
3b+19+b=119
4b+19=119
4b=119-19
4b=100
b=25
a=119-25
a=94
a:b=3 rest 19
a=3b+19
3b+19+b=119
4b+19=119
4b=119-19
4b=100
b=25
a=119-25
a=94
a+b=119
a:b = 3 rest 19 ⇒teorema impartirii cu rest a=b x 3+19
apoi inlocuiesti in suma:
b x 3+19+b=119⇒
4b = 110⇒ b = 27,5
a=119-27,5⇒ a=91,5
a:b = 3 rest 19 ⇒teorema impartirii cu rest a=b x 3+19
apoi inlocuiesti in suma:
b x 3+19+b=119⇒
4b = 110⇒ b = 27,5
a=119-27,5⇒ a=91,5
