Question

$$a \div b = - 5$$

Solve for b

$b=-\frac{a}{5}$
$a\neq 0$

Steps for Solving Linear Equation

Variable $b$ cannot be equal to $0$ since division by zero is not defined. Multiply both sides of the equation by $b$.

$$a=-5b$$

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

$$-5b=a$$

Divide both sides by $-5$.

$$\frac{-5b}{-5}=\frac{a}{-5}$$

Dividing by $-5$ undoes the multiplication by $-5$.

$$b=\frac{a}{-5}$$

Divide $a$ by $-5$.

$$b=-\frac{a}{5}$$

Variable $b$ cannot be equal to $0$.

$$b=-\frac{a}{5}\text{, }b\neq 0$$

Solve for a

$a=-5b$
$b\neq 0$
