Question

resolva a equacao:
10x - 5 (1+x)=3 (2x -2)

Answer 1

$10x - 5 (1+x)=3 (2x -2)\to \\\\ 10x - 5-5x=6x -6\to \\\\10x-5x-6x=-6+5\to \\\\-x=-1(-1)\to \\\\ x=1$

Answer 2

$10x-5(1+x)=3(2x-2)$

$10x-5-5x=3(2x-2)$

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

$5x-5=3*2x-3*2$

$5x-5=6x-3*2$

$5x-5=6x-6$

$-5=6x-6-5x$

$-5=x-6$

$-x=5-6 * (-1)$

$x=-5+6$

$x=1$
