x=400x=400

Explanation:

x/20 - 10 = 10x2010=10

Add 1010 to both sides,

x/20=20x20=20

Multiply 2020 to both sides,

x=400x=400

x=400x=400

Explanation:

Start with the equation
(x/20)-10=10(x20)10=10

Add 1010 to both sides to cancel out (-10)(10)
x/20-10(+10)=10(+10)x2010(+10)=10(+10)

Simplify
x/20=20x20=20

Multiply by 2020 to cancel out (x/20)(x20)
x/20(*20)=20(*20)x20(20)=20(20)

Simplify
x=400x=400
