Question

1+ 3/2+x= 1/2 ( é 3 sobre 2+x)

Answer 1

$1+\frac{3}{2+x} =\frac{1}{2}$

$1+\frac{3}{2}+\frac{1}{2+x}-\frac{1}{2}=0$

$\frac{1}{1} +\frac{3}{2}-\frac{1}{2}+\frac{1}{2+x} =0$

$\frac{1*2}{1*2}+\frac{3}{2}-\frac{1}{2} + \frac{1}{2+x}$

$\frac{2}{2} +\frac{3}{2}-\frac{1}{2}+\frac{1}{2+x} =0$

$\frac{2+3-1}{2} + \frac{1}{2+x} =0$

$\frac{4}{2}+\frac{1}{2+x}=0$

$2+1*(2+x)^{-1}$

2 + $(2 + x)^{-1}$

2 + $\frac{1}{2+x}$ = $\frac{2+1}{2+x}$  = $\frac{3}{2+x}$

Resposta :  $\frac{3}{2+x}$
