Answer:

x=6

Explanation:

4x-4=2x+8

$\hookrightarrow$ Add 4 to both sides:

$\longmapsto 4x-4+4=2x+8+4$

$\longmapsto 4x=2x+12$

$\hookrightarrow$ Subtract 2x from both sides:

$\longmapsto x-2x=2x+12-2x$

$\longmapsto2x=12$

$\hookrightarrow$ Divide both sides by 2:

$\longmapsto(2x)/(2)=(12)/(2)$

$\longmapsto x=6$
