Question

x/3 + 6/5 = 12/6 não consegui fazer :(

Answer 1

x/3 + 6/5 = 12/6

$\frac{x}{3} + \frac{6}{5} = \frac{12}{6}$

faça o mmc que dá 30

$\frac{x.10}{3} + \frac{6 \times 6}{5} = \frac{12 \times 5}{6}$

$\frac{10x + 36}{30} = \frac{60}{30}$

$10x + 36 = \frac{60 \times 30}{30}$

$10 \times = 60 - 36 \\ 10x = 24 = \frac{24}{10}$

a resposta é 2,4 ou 24/10

Answer 2

X/3 + 6/5 = 12/6
X/3 + 6/5 = 2
Mmc (3,5) = 15
(5x + 3.6)/15 = 15.2/15
5x + 18 = 30
5x = 30 - 18
5x = 12
x = 12/5
