Question

solutia ecuatiei 7/23+5/23-x/23=2/23

Answer 1

Bună! ⭐

_________

$\frac{7}{23}+\frac{5}{23}-\frac{x}{23} =\frac{2}{23} <=>$

$<=> -\frac{x}{23}=-\frac{7}{23}-\frac{5}{23}+\frac{2}{23} <=>$

$<=> - \frac{x}{23} =\frac{-7-5+2}{23} <=>$

$<=> -\frac{x}{23 } =-\frac{10}{23} => {\boxed{\mathbf {x=10}}$

sau

$\frac{7}{23}+\frac{5}{23}-\frac{x}{23} =\frac{2}{23} /*23<=>$

$<=>7+5-x=2<=>$

$<=> 12-2=x => {\boxed{\mathbf {10=x}}$
