Question

determine o valor das variáveis.​

Answer 1

Explicação passo-a-passo:

$\frac{x}{6} = \frac{(8 + 4}){8} = > \frac{x}{6} = \frac{12}{8} = 8x = 6.12 = > 8x = 72 = > x = \frac{72}{8} = > x = 9$

$\frac{10 + y}{10} = \frac{12}{8} = > \frac{10 + y}{10} = \frac{3}{2} = > 2.(10 + y) = 10.3 = > 20 + 2y = 30 = > 2y = 30 - 20 = > 2y = 10 = > y = \frac{10}{2} = > y = 5$
