Question

ma ajuta careva ? va rog

Answer 1

$\frac{x}{10}- \frac{1}{2} ( \frac{x}{2}- \frac{2x+1}{10}) = \frac{1-x}{4}$
$\frac{x}{10}- \frac{1}{2}( \frac{5x-2x-1}{10} )= \frac{1-x}{4}$
$\frac{x}{10}- \frac{1}{2}* \frac{3x-1}{10}= \frac{1-x}{4}$
$\frac{2x-3x+1}{20}= \frac{1-x}{4 }$
$\frac{1-x}{20}= \frac{1-x}{4 }$
$4-4x=20-20x$
$-16=-16x$
$x=1$
