Solve x=(-y-1)/2

$$x = ( - y - 1 ) / 2$$

Solve for y

$$y=-2x-1$$

Steps for Solving Linear Equation

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

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

Divide each term of -y-1 by 2 to get -\frac{1}{2}y-\frac{1}{2}.

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

Add \frac{1}{2} to both sides.

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

Multiply both sides by -2.

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

Dividing by -\frac{1}{2} undoes the multiplication by -\frac{1}{2}.

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

Divide x+\frac{1}{2} by -\frac{1}{2} by multiplying x+\frac{1}{2} by the reciprocal of -\frac{1}{2}.

$$y=-2x-1$$

Solve for x

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

Solution Steps

Divide each term of -y-1 by 2 to get -\frac{1}{2}y-\frac{1}{2}.

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