Solve y=x/x-7

$$y = \frac { x } { x - 7 }$$

Solve for x

$$x=\frac{7y}{y-1}$$

$$y\neq 1$$

Steps for Solving Linear Equation

Variable x cannot be equal to 7 since division by zero is not defined. Multiply both sides of the equation by x-7.

$$y\left(x-7\right)=x$$

Use the distributive property to multiply y by x-7.

$$yx-7y=x$$

Subtract x from both sides.

$$yx-7y-x=0$$

Add 7y to both sides. Anything plus zero gives itself.

$$yx-x=7y$$

Combine all terms containing x.

$$\left(y-1\right)x=7y$$

Divide both sides by y-1.

$$\frac{\left(y-1\right)x}{y-1}=\frac{7y}{y-1}$$

Dividing by y-1 undoes the multiplication by y-1.

$$x=\frac{7y}{y-1}$$

Variable x cannot be equal to 7.

$$x=\frac{7y}{y-1}\text{, }x\neq 7$$

Solve for y

$$y=\frac{x}{x-7}$$

$$x\neq 7$$
