$x=400$

$x/20 - 10 = 10$

Add $10$ to both sides,

$x/20=20$

Multiply $20$ to both sides,

$x=400$

$x=400$

Start with the equation
$(x/20)-10=10$

Add $10$ to both sides to cancel out $(-10)$
$x/20-10(+10)=10(+10)$

Simplify
$x/20=20$

Multiply by $20$ to cancel out $(x/20)$
$x/20(*20)=20(*20)$

Simplify
$x=400$
