Question

gostaria de determinar o conjunto de solução da equação 4/2(x-2)=-1/2(2x+3)

Answer 1

Resposta:

$\frac{4}{2}\left(x-2\right)=-\frac{1}{2}\left(2x+3\right)$

$\frac{4}{2}\left(x-2\right)=2x-4$

$-\frac{1}{2}\left(2x+3\right)=-x-\frac{3}{2}$

$temos:$

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

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

$2x=-x+\frac{5}{2}$

$2x+x=-x+\frac{5}{2}+x$

$3x=\frac{5}{2}$

$x=\frac{5}{6}$
