Question

x/y=5/3 x ➕ y=24

Aflați x, y​

Answer 1

Salut! =)

x / y = 5 / 3

x + y = 24

-------------------

x , y = ?

x / y = 5 / 3 => 3x = 5y => x = 5y / 3

Inlocuim in a doua formula

5y / 3 + y = 24

Aducem la acelasi numitor ( 3 )

5y + 3y = 72

8y = 72

y = 9

x = ( 5 × 9 ) / 3

x = 5 × 3

x = 15

Bafta! =)
