Solve y=4x-12quadI

$$y = 4 x - 12 \quad I$$

Solve for I

$$I=\frac{x}{3}-\frac{y}{12}$$

Steps for Solving Linear Equation

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

$$4x-12I=y$$

Subtract 4x from both sides.

$$-12I=y-4x$$

Divide both sides by -12.

$$\frac{-12I}{-12}=\frac{y-4x}{-12}$$

Dividing by -12 undoes the multiplication by -12.

$$I=\frac{y-4x}{-12}$$

Divide y-4x by -12.

$$I=\frac{x}{3}-\frac{y}{12}$$

Solve for x

$$x=\frac{y+12I}{4}$$

Steps for Solving Linear Equation

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

$$4x-12I=y$$

Add 12I to both sides.

$$4x=y+12I$$

Divide both sides by 4.

$$\frac{4x}{4}=\frac{y+12I}{4}$$

Dividing by 4 undoes the multiplication by 4.

$$x=\frac{y+12I}{4}$$

Divide y+12I by 4.

$$x=\frac{y}{4}+3I$$
