Question

 resolver 3/4(2x+4)=x+19

Answer 1

$\frac{3}{4} (2x+4)=x+19$
$3(2x+4)=4(x+19)$
$3(2x+4)=4x+76$
$6x+12=4x+76$
$6x-4x=76-12$
$2x=64$
$x=32$

Answer 2

al go sencillo ya primero multiplicas bueno asi ya:
3/4(2x+4)=x+19
6x/4+3=x+19                                notaÑ 3/4*4=12/4=3
6x-x=19(4)-3
5x=76-3
5x=73
x=73/5
