Solve for x 9-x/10=0

$9 - \frac{x}{10} = 0$

Subtract $9$ from both sides of the equation.

$- \frac{x}{10} = - 9$

Multiply both sides of the equation by $- 10$ .

$- 10 (- \frac{x}{10}) = - 10 \cdot - 9$

Simplify both sides of the equation.

Simplify the left side.

Simplify $- 10 (- \frac{x}{10})$ .

Cancel the common factor of $10$ .

Move the leading negative in $- \frac{x}{10}$ into the numerator.

$- 10 \frac{- x}{10} = - 10 \cdot - 9$

Factor $10$ out of $- 10$ .

$10 (- 1) \frac{- x}{10} = - 10 \cdot - 9$

Cancel the common factor.

$10 \cdot - 1 \frac{- x}{10} = - 10 \cdot - 9$

Rewrite the expression.

$- - x = - 10 \cdot - 9$

Multiply.

Multiply $- 1$ by $- 1$ .

$1 x = - 10 \cdot - 9$

Multiply $x$ by $1$ .

$x = - 10 \cdot - 9$

Simplify the right side.

Multiply $- 10$ by $- 9$ .

$x = 90$
