Solve for x -3x-2=7

$- 3 x - 2 = 7$

Step 1

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

Add $2$ to both sides of the equation.

$- 3 x = 7 + 2$

Add $7$ and $2$ .

$- 3 x = 9$

Step 2

Divide each term in $- 3 x = 9$ by $- 3$ and simplify.

Divide each term in $- 3 x = 9$ by $- 3$ .

$\frac{- 3 x}{- 3} = \frac{9}{- 3}$

Simplify the left side.

Cancel the common factor of $- 3$ .

Cancel the common factor.

$\frac{- 3 x}{- 3} = \frac{9}{- 3}$

Divide $x$ by $1$ .

$x = \frac{9}{- 3}$

Simplify the right side.

Divide $9$ by $- 3$ .

$x = - 3$
