Question

Escreva as equações na forma reduzida
(2x+1)*( \frac{x}{2}-2)=x+5 
( \frac{2x}{3} +1)*3x=5*(x-4)+20[/

Answer 1

$(2x+1)*( \frac{x}{2}-2)=x+5 ( \frac{2x}{3} +1)*3x=5*(x-4)+20$
$x-4x+0,5x-2=2 x^{2}+3=5x$
$3,5x-2=x+5.(2 x^{2}+3)=5x 3,5x-2=2 x^{3}+3x+10 x^{2}+15-5=0$
$0,5x-17-2 x^{3} -10 x^{2}$
