Solve for x 3x-15=3

$3 x - 15 = 3$

Step 1

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

Add $15$ to both sides of the equation.

$3 x = 3 + 15$

Add $3$ and $15$ .

$3 x = 18$

Step 2

Divide each term in $3 x = 18$ by $3$ and simplify.

Divide each term in $3 x = 18$ by $3$ .

$\frac{3 x}{3} = \frac{18}{3}$

Simplify the left side.

Cancel the common factor of $3$ .

Cancel the common factor.

$\frac{3 x}{3} = \frac{18}{3}$

Divide $x$ by $1$ .

$x = \frac{18}{3}$

Simplify the right side.

Divide $18$ by $3$ .

$x = 6$
