Question

1. Resolva as seguintes aquapes tu watiwal, sendo - U = R confirme o exemplo
$a \frac{x}{3} = 5$
$b \frac{x}{5} = 2$
$c \frac{x}{ - 12} = 4$
$d \: \frac{2x}{7} = 6$
​

Answer 1

Explicação passo-a-passo:

.

$\dfrac{x}{3} = 5$

$x = 15$

.

$\dfrac{x}{5} = 2$

$x = 10$

.

$\dfrac{x}{ - 12} = 4$

$x = - 48$

.

$\dfrac{2x}{7} = 6$

$2x = 42$

$x = \dfrac{42}{2}$

$x = 21$
