Solve V_{2}=P*20/4P

$$V _ { 2 } = \frac { P \times 20 } { 4 P }$$

Solve for P

$$P\neq 0$$

$$V_{2}=5\text{ and }P\neq 0$$

Steps for Solving Linear Equation

Variable P cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 4P.

$$V_{2}\times 4P=P\times 20$$

Subtract P\times 20 from both sides.

$$V_{2}\times 4P-P\times 20=0$$

Multiply -1 and 20 to get -20.

$$V_{2}\times 4P-20P=0$$

Combine all terms containing P.

$$\left(V_{2}\times 4-20\right)P=0$$

The equation is in standard form.

$$\left(4V_{2}-20\right)P=0$$

Divide 0 by 4V_{2}-20.

$$P=0$$

Variable P cannot be equal to 0.

$$P\in \emptyset$$

Solve for V_2

$$V_{2}=5$$

$$P\neq 0$$

Steps for Solving Linear Equation

Cancel out 4P in both numerator and denominator.

$$V_{2}=5$$
