$x=12$

Because the denominators need to be the same number, so you multiply $x/2$ by $3/3$ and so it will equal

$(3x)/6-x/6=4$

Then, you subtract and it will equal

$(2x)/6=4$

Then, you follow PEMDAS and multiply $6$ on both sides to eliminate the divide by 6, so it would equal

$2x=24$

You divide by $2$ on both sides and $x$ will equal $12$ .
