Ten less than a number is equal the same number divided by 2 what is the number

x-10=x/2

Simplify both sides of the equation.

x-10 = x / 2

x+-10 = 1/2 x

x-10 = 1/2 x

Subtract 1/2 x from both sides.

x-10-1/2 x = 1/2 x - 1/2 x

1/2 x-10 = 0

Add 10 to both sides.

1/2 x-10+10 = 0+10

1/2 x = 10

Multiply both sides by 2.

2 * (1/2 x) = (2) * (10)

Your answer should be: x = 20
