Răspuns :
Fie cele doua numere x si y .
x-y=43
x=2y-44
Inlocuiesti : 2y-44-y=43 => 2y-y=43+44 => y=87
=> x=130 (adica 2 ori 87 minus 44 )
x-y=43
x=2y-44
Inlocuiesti : 2y-44-y=43 => 2y-y=43+44 => y=87
=> x=130 (adica 2 ori 87 minus 44 )
Notam cele doua numere prin a si b
a-b=43
a=2b-44
2b-44-b=43 => 2b-b=44+44
b=87
a=2*87-44=130
