Question

Suma a trei numere este 125.Daca adunam pe rand fiecare dintre aceste numere cu același număr obținem 46,61 respectiv 66 care sunt cele 3 numere?
(Cu rezolvare :D nu doar răspunsul corect )

Answer 1

a+b+c=125

a+x=46

a=46-x

b+x=61

b=61-x

c+x=66

c=66-x

46-x+61-x+66-x=125

173-3x=125

3x=173-125

3x=48

x=48:3

x=16

a=46-16=30

b=61-16=45

c=66-16=50

Answer 2

$a + b + c = 125\\\\a + x=46\\\\\boxed{a = 46 - x}\\\\b + x = 61\\\\\boxed{b = 61 - x}\\\\c + x = 66\\\\\boxed{c = 66 - x}\\\\\:\: inlocuim \:in \:suma\: si\: vom\: avea\\\\46 - x + 61 - x + 66 - x = 125\\\\173 - 3x = 125\\\\3x = 173 - 125\\\\3x =48\\\\x = 48 : 3\\\\\boxed{x = 16}\\\\a = 46 - 16\\\\ \boxed{a = 30}\\\\b = 61 - 16\\\\\boxed{b = 45}\\\\c = 66 - 16\\\\\boxed{c = 50}$
