Solve y=2x-1/x-4

$$y= \frac{ 2x-1 }{ x-4 }$$

Solve for x

$$x=-\frac{1-4y}{y-2}$$

$$y\neq 2$$

Steps for Solving Linear Equation

Variable x cannot be equal to 4 since division by zero is not defined. Multiply both sides of the equation by x-4.

$$y\left(x-4\right)=2x-1$$

Use the distributive property to multiply y by x-4.

$$yx-4y=2x-1$$

Subtract 2x from both sides.

$$yx-4y-2x=-1$$

Add 4y to both sides.

$$yx-2x=-1+4y$$

Combine all terms containing x.

$$\left(y-2\right)x=-1+4y$$

The equation is in standard form.

$$\left(y-2\right)x=4y-1$$

Divide both sides by y-2.

$$\frac{\left(y-2\right)x}{y-2}=\frac{4y-1}{y-2}$$

Dividing by y-2 undoes the multiplication by y-2.

$$x=\frac{4y-1}{y-2}$$

Variable x cannot be equal to 4.

$$x=\frac{4y-1}{y-2}\text{, }x\neq 4$$

Solve for y

$$y=-\frac{1-2x}{x-4}$$

$$x\neq 4$$
