Solve for x y=-3x

$y = - 3 x$

Step 1

Rewrite the equation as $- 3 x = y$ .

$- 3 x = y$

Step 2

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

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

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

Simplify the left side.

Cancel the common factor of $- 3$ .

Cancel the common factor.

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

Divide $x$ by $1$ .

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

Simplify the right side.

Move the negative in front of the fraction.

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