How to solve x = b / (- 12)

1. Factor the equation (x + 2)(x + 3) = 0. 2. Set each factor equal to zero: x + 2 = 0 and x + 3 = 0. 3. Solve for x: x = -2 and x = -3.

$$x=b:(-12)$$

$b=-12x$

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

$$\frac{b}{-12}=x$$

The equation is in standard form.

$$-\frac{1}{12}b=x$$

Multiply both sides by $-12$.

$$\frac{-\frac{1}{12}b}{-\frac{1}{12}}=\frac{x}{-\frac{1}{12}}$$

Dividing by $-\frac{1}{12}$ undoes the multiplication by $-\frac{1}{12}$.

$$b=\frac{x}{-\frac{1}{12}}$$

Divide $x$ by $-\frac{1}{12}$ by multiplying $x$ by the reciprocal of $-\frac{1}{12}$.

$$b=-12x$$

$x=-\frac{b}{12}$
