Solve 3=b/ax

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

Solve for a

$$a=\frac{bx}{3}$$

$$x\neq 0\text{ and }b\neq 0$$

Steps for Solving Linear Equation

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

$$3a=bx$$

Divide both sides by 3.

$$\frac{3a}{3}=\frac{bx}{3}$$

Dividing by 3 undoes the multiplication by 3.

$$a=\frac{bx}{3}$$

Variable a cannot be equal to 0.

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

Solve for b

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

$$a\neq 0\text{ and }x\neq 0$$

Steps for Solving Linear Equation

Multiply both sides of the equation by a.

$$3a=bx$$

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

$$bx=3a$$

The equation is in standard form.

$$xb=3a$$

Divide both sides by x.

$$\frac{xb}{x}=\frac{3a}{x}$$

Dividing by x undoes the multiplication by x.

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