Question

Resolva as seguintes proporções:

Answer 1

Resposta:

a)

$35x = 105$

$x = \frac{105}{35}$

$x = 3$

b)

$10x = 350$

$x = \frac{350}{10}$

$x = 35$

c)

$7 x - 42 = 49$

$7x = 49 + 42$

$7x = 91$

$x = \frac{91}{7}$

$x = 13$

d)

$150x + 90 = - 210$

$150x = - 210 - 90$

$150x = - 300$

$x = \frac{ - 300}{150}$

$x = -2$
