Solve for x 3x--9=3

$3 x - - 9 = 3$

Step 1

Replace all occurrences of $-$ $-$ with a single $+$ . Two consecutive minus signs have the same mathematical meaning as a single plus sign because $- 1 \cdot - 1 = 1$

$3 x + 9 = 3$

Step 2

Move all terms not containing $x$ to the right side of the equation.

Subtract $9$ from both sides of the equation.

$3 x = 3 - 9$

Subtract $9$ from $3$ .

$3 x = - 6$

Step 3

Divide each term in $3 x = - 6$ by $3$ and simplify.

Divide each term in $3 x = - 6$ by $3$ .

$\frac{3 x}{3} = \frac{- 6}{3}$

Simplify the left side.

Cancel the common factor of $3$ .

Cancel the common factor.

$\frac{3 x}{3} = \frac{- 6}{3}$

Divide $x$ by $1$ .

$x = \frac{- 6}{3}$

Simplify the right side.

Divide $- 6$ by $3$ .

$x = - 2$
