Question

$$a/b=3/4$$

Solve for a

$a=\frac{3b}{4}$
$b\neq 0$

Steps for Solving Linear Equation

Multiply both sides of the equation by $4b$, the least common multiple of $b,4$.

$$4a=3b$$

Divide both sides by $4$.

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

Dividing by $4$ undoes the multiplication by $4$.

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

Show Solution

Solve for b

$b=\frac{4a}{3}$
$a\neq 0$

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 $4b$, the least common multiple of $b,4$.

$$4a=3b$$

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

$$3b=4a$$

Divide both sides by $3$.

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

Dividing by $3$ undoes the multiplication by $3$.

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

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

$$b=\frac{4a}{3}\text{, }b\neq 0$$
