Solve 1+x=1-0.5y

$$1+x=1-0.5y$$

Solve for x

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

Solution Steps

Subtract 1 from both sides.

$$x=1-0.5y-1$$

Subtract 1 from 1 to get 0.

$$x=-0.5y$$

Solve for y

$$y=-2x$$

Steps for Solving Linear Equation

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

$$1-0.5y=1+x$$

Subtract 1 from both sides.

$$-0.5y=1+x-1$$

Subtract 1 from 1 to get 0.

$$-0.5y=x$$

Multiply both sides by -2.

$$\frac{-0.5y}{-0.5}=\frac{x}{-0.5}$$

Dividing by -0.5 undoes the multiplication by -0.5.

$$y=\frac{x}{-0.5}$$

Divide x by -0.5 by multiplying x by the reciprocal of -0.5.

$$y=-2x$$
