Question

A) x-5 - 2(x-1) = 2(3-x) Por favor me urge

Answer 1

$\bf{x-5 - 2(x-1) = 2(3-x)$

$x-5-2x+2=6-2x$

$-x-3=6-2x$

$-x=6-2x+3$

$-x=-2x+9$

$-x+2x=9$

$\boxed{\bf{x = 9}}$

$\bf{Comprobaci\'on:$

$x-5-2(x-1)=2(3-x)$

$9-5-2\times(9-1)=2\times(3-9)$

$9-5-2\times8=2\times(3-9)$

$9-5-2\times8=2\times-6$

$9-5-16=2\times-6$

$9-5-16=-12$

$4-6=-12$

$-12=-12$
