Solve L=(n0/N)(28)^2

$$L = ( \frac { n 0 } { N } ) ( 28 ) ^ { 2 }$$

Solve for N

$$\left\{\begin{matrix}N=\frac{784n_{0}}{L}\text{, }&n_{0}\neq 0\text{ and }L\neq 0\\N\neq 0\text{, }&L=0\text{ and }n_{0}=0\end{matrix}\right.$$

Steps for Solving Linear Equation

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

$$LN=n_{0}\times 28^{2}$$

Calculate 28 to the power of 2 and get 784.

$$LN=n_{0}\times 784$$

The equation is in standard form.

$$LN=784n_{0}$$

Divide both sides by L.

$$\frac{LN}{L}=\frac{784n_{0}}{L}$$

Dividing by L undoes the multiplication by L.

$$N=\frac{784n_{0}}{L}$$

Variable N cannot be equal to 0.

$$N=\frac{784n_{0}}{L}\text{, }N\neq 0$$

Solve for L

$$L=\frac{784n_{0}}{N}$$

$$N\neq 0$$
