Solve for x 3x-y=9

$3 x - y = 9$

Step 1

Add $y$ to both sides of the equation.

$3 x = 9 + y$

Step 2

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

Divide each term in $3 x = 9 + y$ by $3$ .

$\frac{3 x}{3} = \frac{9}{3} + \frac{y}{3}$

Simplify the left side.

Cancel the common factor of $3$ .

Cancel the common factor.

$\frac{3 x}{3} = \frac{9}{3} + \frac{y}{3}$

Divide $x$ by $1$ .

$x = \frac{9}{3} + \frac{y}{3}$

Simplify the right side.

Divide $9$ by $3$ .

$x = 3 + \frac{y}{3}$
