Question

diferenta a 2 numere este 144 daca se imparte primul numar la al doilea se optine citul 7 si restul 18 afla suma celor 2 numere

Answer 1

a-b=144
a:b=7 rest 18
a+b=?
a=144+b
a=7b+18
Deci 144+b=7b+18→7b+18-b=144
6b+18=144→6b=144-18=126
b=126:6=21
a=144+21=165

Answer 2

a-b=144
a:b=7 rest 18
b=/---/
a=/---/---/---/---/---/---/---/+18
8 p = 144-18
8 p = 126
1 p = 126:6
1 p = 21
b = 21
a = 21×7+18
a =147+18
a =165
