Question

como se resuelve 3/4 ( 2x +4 ) = x +19

Answer 1

Resolver.

3/4(2x + 4) = x + 19
3(2x + 4) = 4(x + 19)
6x + 12 = 4x + 76
6x - 4x = 76 - 12
2x = 64
x = 64/2
x = 32

Respuesta.
x = 32

Answer 2

$\frac{3}{4}(2x +4)= x + 19$

$\frac{6x + 12}{4} = x + 19$

$6x + 12 = 4x + 76$
$6x-4x = 76 - 12$
$2x = 64$
$x = \frac{64}{2} = 32$    ⇒  x = 32

comprobamos

$\frac{3}{4} (64+4) = 32 + 19 =$
$\frac{3}{4} (68) = 51$
51 = 51
