$x = 400$ $x=400$

$\frac{x}{20} - 10 = 10$ $x/20 - 10 = 10$

Add $10$ $10$ to both sides,

$\frac{x}{20} = 20$ $x/20=20$

Multiply $20$ $20$ to both sides,

$x = 400$ $x=400$

$x = 400$ $x=400$

Start with the equation
$(\frac{x}{20}) - 10 = 10$ $(x/20)-10=10$

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

Simplify
$\frac{x}{20} = 20$ $x/20=20$

Multiply by $20$ $20$ to cancel out $(\frac{x}{20})$ $(x/20)$
$\frac{x}{20} (\cdot 20) = 20 (\cdot 20)$ $x/20(*20)=20(*20)$

Simplify
$x = 400$ $x=400$
