Question

x + y = 29 x menos y = 5​

Answer 1

Resposta: X= 17 e Y= 12

Explicação passo-a-passo:

(I) X+Y= 29

(II) X-Y= 5

Somando (I) e (II)

2x + 0 = 34

X= 34/2

X= 17

Answer 2

Ok , Vamos lá !!

Valor de X

$\begin{gathered}\begin{cases}\sf{x + y = 29}\\\sf{x - y = 5}\end{cases}\end{gathered}{}$

$\sf {2x = 34}$

$\sf {x = \dfrac{34}{2} }$

$\red{\sf {x = 17}}$

Valor de Y

$\sf {x + y = 29}$

$\sf {17 + y = 29}$

$\sf {y = 29 - 17}$

$\red{\sf {y = 12}}$

Bons estudos .
