Solve for x 3(x+y)=y

$3 (x + y) = y$

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

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

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

Simplify the left side.

Cancel the common factor of $3$ .

Cancel the common factor.

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

Divide $x + y$ by $1$ .

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

Subtract $y$ from both sides of the equation.

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