Solve 18=-x/2y

$$18=- \frac{ x }{ 2y }$$

Solve for x

$$x=-36y$$

$$y\neq 0$$

Steps for Solving Linear Equation

Multiply both sides of the equation by 2y.

$$36y=-x$$

Swap sides so that all variable terms are on the left hand side.

$$-x=36y$$

Divide both sides by -1.

$$\frac{-x}{-1}=\frac{36y}{-1}$$

Dividing by -1 undoes the multiplication by -1.

$$x=\frac{36y}{-1}$$

Divide 36y by -1.

$$x=-36y$$

Solve for y

$$y=-\frac{x}{36}$$

$$x\neq 0$$

Steps for Solving Linear Equation

Variable y cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 2y.

$$36y=-x$$

Divide both sides by 36.

$$\frac{36y}{36}=-\frac{x}{36}$$

Dividing by 36 undoes the multiplication by 36.

$$y=-\frac{x}{36}$$

Variable y cannot be equal to 0.

$$y=-\frac{x}{36}\text{, }y\neq 0$$
