Solve x+1=-y+0.8

$$x+1=-y+0.8$$

Solve for x

$$x=-\left(y+0.2\right)$$

Solution Steps

Subtract 1 from both sides.

$$x=-y+0.8-1$$

Subtract 1 from 0.8 to get -0.2.

$$x=-y-0.2$$

Solve for y

$$y=-x-0.2$$

Steps for Solving Linear Equation

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

$$-y+0.8=x+1$$

Subtract 0.8 from both sides.

$$-y=x+1-0.8$$

Subtract 0.8 from 1 to get 0.2.

$$-y=x+0.2$$

Divide both sides by -1.

$$\frac{-y}{-1}=\frac{x+0.2}{-1}$$

Dividing by -1 undoes the multiplication by -1.

$$y=\frac{x+0.2}{-1}$$

Divide x+0.2 by -1.

$$y=-\left(x+0.2\right)$$
