x﹣ $\text{[math]}$ x= $\text{[math]}$	1﹣ $\text{[math]}$ x= $\text{[math]}$	8x+ $\text{[math]}$ = $\text{[math]}$	$\text{[math]}$ ÷x= $\text{[math]}$
$\text{[math]}$ x÷ $\text{[math]}$ = $\text{[math]}$	3÷ $\text{[math]}$ x= $\text{[math]}$	$\text{[math]}$ x÷3= $\text{[math]}$	8x× $\text{[math]}$ = $\text{[math]}$ ．
