Question

{(x + 3)/5} - 2/3 = 14 / 6​

Answer 1

Respuesta:

x = 12

Explicación paso a paso:

$( \frac{x + 3}{5} ) - \frac{2}{3} = \frac{14}{6} \\ ( \frac{x + 3}{5} ) - \frac{2}{3} = \frac{7}{3} \\ 15( \frac{x + 3}{5} ) - 15( \frac{2}{3} ) = 15( \frac{7}{3} ) \\ 3(x + 3) - 5 \times 2 = 5 \times 7 \\ 3x + 9 - 10 = 35 \\ 3x = 35 - 9 + 10 \\ 3x = 36 \\ x = \frac{36}{3} \\ x = 12$
