Solve 180/45=pi/x

$$\frac { 180 } { 45 } = \frac { \pi } { x }$$

Solve for x

$$x=\frac{\pi }{4}\approx 0.785398163$$

Steps for Solving Linear Equation

Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 45x, the least common multiple of 45,x.

$$x\times 180=45\pi$$

The equation is in standard form.

$$180x=45\pi$$

Divide both sides by 180.

$$\frac{180x}{180}=\frac{45\pi }{180}$$

Dividing by 180 undoes the multiplication by 180.

$$x=\frac{45\pi }{180}$$

Divide 45\pi by 180.

$$x=\frac{\pi }{4}$$

Variable x cannot be equal to 0.

$$x=\frac{\pi }{4}\text{, }x\neq 0$$
