Solve y-2x-1=0

$$y-2x-1=0$$

Solve for x

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

Steps for Solving Linear Equation

Subtract y from both sides. Anything subtracted from zero gives its negation.

$$-2x-1=-y$$

Add 1 to both sides.

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

The equation is in standard form.

$$-2x=1-y$$

Divide both sides by -2.

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

Dividing by -2 undoes the multiplication by -2.

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

Divide -y+1 by -2.

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

Solve for y

$$y=2x+1$$

Solution Steps

Add 2x to both sides. Anything plus zero gives itself.

$$y-1=2x$$

Add 1 to both sides.

$$y=2x+1$$
