Question

Calculem o valor de x :

$\frac{ \times + 7}{4 } = \frac{11 - \times }{2}$
​

Answer 1

Oii!

$\frac{x + 7}{4} = \frac{11 - x}{2} =$

$2(x + 7) = 4(11 - x)$

$2x + 14 = 44 - 4x$

$2x + 4x = 44 - 14$

$6x = 30$ ( 30 ÷ 6 = 5)

$x = 5$

>>> x = 5

Answer 2

Explicação:

$\frac{x+ 7}{4} = \frac{11 - x}{2}$

$(x + 7)2 = 4(11 - x)$

$2x + 14 = 44 - 4x$

$2x + 4x = 44 - 14$

$6x = 30$

$x = \frac{30}{6}$

$x = 5$
