Solve y-x-1=0

$$y-x-1=0$$

Solve for x

$$x=y-1$$

Steps for Solving Linear Equation

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

$$-x-1=-y$$

Add 1 to both sides.

$$-x=-y+1$$

The equation is in standard form.

$$-x=1-y$$

Divide both sides by -1.

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

Dividing by -1 undoes the multiplication by -1.

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

Divide -y+1 by -1.

$$x=y-1$$

Solve for y

$$y=x+1$$

Solution Steps

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

$$y-1=x$$

Add 1 to both sides.

$$y=x+1$$
