Solve x=I/E

$$x = \frac { I } { E }$$

Solve for E

$$\left\{\begin{matrix}E=\frac{I}{x}\text{, }&I\neq 0\text{ and }x\neq 0\\E\neq 0\text{, }&x=0\text{ and }I=0\end{matrix}\right.$$

Steps for Solving Linear Equation

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

$$xE=I$$

Divide both sides by x.

$$\frac{xE}{x}=\frac{I}{x}$$

Dividing by x undoes the multiplication by x.

$$E=\frac{I}{x}$$

Variable E cannot be equal to 0.

$$E=\frac{I}{x}\text{, }E\neq 0$$

Solve for I

$$I=Ex$$

$$E\neq 0$$

Solution Steps

Multiply both sides of the equation by E.

$$xE=I$$

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

$$I=xE$$
