Question

$$-9a+b=-12$$

Solve for a

$a=\frac{b+12}{9}$

Steps for Solving Linear Equation

Subtract $b$ from both sides.

$$-9a=-12-b$$

The equation is in standard form.

$$-9a=-b-12$$

Divide both sides by $-9$.

$$\frac{-9a}{-9}=\frac{-b-12}{-9}$$

Dividing by $-9$ undoes the multiplication by $-9$.

$$a=\frac{-b-12}{-9}$$

Divide $-12-b$ by $-9$.

$$a=\frac{b}{9}+\frac{4}{3}$$
