Question

Me ajudem!
$\frac{3}{4}$+$\frac{1}{x}$=$\frac{11}{12}$

Answer 1

3 + 1   =  11
4    x       12

18x +24 =  22x
   24x         24x

18x + 24 = 22x
24 = 22x - 18x
24 = 4x
4x = 24
x = 24/4
x = 6

Resp.: x = 6
------------------------------------------
mmc (12,4) = 24

12,4: 2
6,4: 2
3,2: 2
3,1: 3
1,1       = 2.2.2.3 = 8.3 = 24 . x = 24x

mmc = 24.x

Answer 2

  $\frac{1}{x} = \frac{11}{12}- \frac{3}{4}$
$\frac{1}{X}= \frac{11}{12}- \frac{9}{12}$
$\frac{1}{x}= \frac{2}{12}= \frac{1}{6}$
$X=6$
