Solve x-4y+13=0

$$x - 4 y + 13 = 0$$

Solve for x

$$x=4y-13$$

Solution Steps

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

$$x+13=4y$$

Subtract 13 from both sides.

$$x=4y-13$$

Solve for y

$$y=\frac{x+13}{4}$$

Steps for Solving Linear Equation

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

$$-4y+13=-x$$

Subtract 13 from both sides.

$$-4y=-x-13$$

Divide both sides by -4.

$$\frac{-4y}{-4}=\frac{-x-13}{-4}$$

Dividing by -4 undoes the multiplication by -4.

$$y=\frac{-x-13}{-4}$$

Divide -x-13 by -4.

$$y=\frac{x+13}{4}$$
