Solve for x 2x-9=15

$2 x - 9 = 15$

Step 1

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

Add $9$ to both sides of the equation.

$2 x = 15 + 9$

Add $15$ and $9$ .

$2 x = 24$

Step 2

Divide each term in $2 x = 24$ by $2$ and simplify.

Divide each term in $2 x = 24$ by $2$ .

$\frac{2 x}{2} = \frac{24}{2}$

Simplify the left side.

Cancel the common factor of $2$ .

Cancel the common factor.

$\frac{2 x}{2} = \frac{24}{2}$

Divide $x$ by $1$ .

$x = \frac{24}{2}$

Simplify the right side.

Divide $24$ by $2$ .

$x = 12$
