Solve x-4y-8=0

$$x - 4 y - 8 = 0$$

Solve for x

$$x=4\left(y+2\right)$$

Solution Steps

Add 4y to both sides. Anything plus zero gives itself.

$$x-8=4y$$

Add 8 to both sides.

$$x=4y+8$$

Solve for y

$$y=\frac{x-8}{4}$$

Steps for Solving Linear Equation

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

$$-4y-8=-x$$

Add 8 to both sides.

$$-4y=-x+8$$

The equation is in standard form.

$$-4y=8-x$$

Divide both sides by -4.

$$\frac{-4y}{-4}=\frac{8-x}{-4}$$

Dividing by -4 undoes the multiplication by -4.

$$y=\frac{8-x}{-4}$$

Divide -x+8 by -4.

$$y=\frac{x}{4}-2$$
