3x/5 + 17/5=x/5+21/3 procedimiento ​

Answer 1

HΘΙΑ

procedimiento :

$\frac{3x}{5} +\frac{17}{5} =\frac{x}{5} +\frac{21}{3}$

$\frac{3}{5} x+\frac{17}{5} =\frac{1}{5} x+7$

$\frac{3}{5} x+\frac{17}{5} -\frac{1}{5} x=\frac{1}{5} x+7-\frac{1}{5} x$

$\frac{2}{5} x+\frac{17}{5} =7$

$\frac{2}{5} x+\frac{17}{5} -\frac{17}{5} =7-\frac{17}{5}$

$\frac{2}{5} x=\frac{18}{5}$

$(\frac{5}{2} )*(\frac{2}{5} )=(\frac{5}{2} )*(\frac{18}{5} )$

resultado :

✨$x=9$✨
