Question

a/6+a/12+a/2=2

A) {-1/2}. B)4. C)8/3. D)3. E)-2​

Answer 1

Respuesta:

$\frac{a}{6} + \frac{a}{12} + \frac{a}{2} = 2$

$\frac{1}{6} x + \frac{1}{12} x + \frac{1}{2} x = 2$

$\frac{ \frac{1}{6} + \frac{1}{12} + \frac{1}{2} }{12} x = 2$

$\frac{2 + 1 + 6}{12} x = 2$

$\frac{9}{12} x = 2$

$\frac{3}{4} x = 2$

$x = 2 \times \frac{4}{3}$

$x = \frac{12}{ 3}$

$x = 4$
