Question

Me ajudem nessa equação pfv !!! 400 = -4/3x + 800

Answer 1

$400 = -\frac{4}{3}x + 800$
$\frac{4}{3}x = 800 - 400$
$\frac{4}{3}x = 400$
$x = \frac{400.3}{4}$
$x = 100.3$
$\setlength{\fboxsep}{5pt} \setlength{\fboxrule}{1pt} \fbox{\setlength{\fboxsep}{3pt} \setlength{\fboxrule}{1pt} \fbox{\setlength{\fboxsep}{5pt} \setlength{\fboxrule}{1pt} \fbox{x=300}}}$

x vale 300

Espero ter ajudado ^-^

Answer 2

400= -4/3x + 800
4/3x = 800-400
x = 200/4/3
multiplicacao inversa
200/1 x 3/4
600/4
= 150
