Question

diferenta a doua nr este144.daca se amparte primul nr la al doilea.se obtine catul7 si restul18.afla suma celor doua numere.

Answer 1

a-b=144
a:b=7r18=>a=7b+18
7b+18-b=144
6b=144-18
b=126:6
b=21
a=7x21+18=165

a+b=165+21=186

Answer 2

a - b = 144
a : b = 7 rest 18
a = 7b + 18
a + b = ?
7b + 18 - b = 144
6b = 144 - 18 
b = 126 : 6
b = 21
a = 7 * 21 + 18
a = 165
a + b = 165 + 21 = 186
si
b - a = 144
b : a = 7 rest 18
b = 7a + 18
7a + 18 - a = 144
6a = 144 - 18
a = 123 : 6
a = 21
b = 7 * 21 + 18
b = 165
a + b = 21 + 165 = 186
