Solve I=t/t+1

$$I = \frac { t } { t + 1 }$$

Solve for t

$$t=-\frac{I}{I-1}$$

$$I\neq 1$$

Steps for Solving Linear Equation

Variable t cannot be equal to -1 since division by zero is not defined. Multiply both sides of the equation by t+1.

$$I\left(t+1\right)=t$$

Use the distributive property to multiply I by t+1.

$$It+I=t$$

Subtract t from both sides.

$$It+I-t=0$$

Subtract I from both sides. Anything subtracted from zero gives its negation.

$$It-t=-I$$

Combine all terms containing t.

$$\left(I-1\right)t=-I$$

Divide both sides by I-1.

$$\frac{\left(I-1\right)t}{I-1}=-\frac{I}{I-1}$$

Dividing by I-1 undoes the multiplication by I-1.

$$t=-\frac{I}{I-1}$$

Variable t cannot be equal to -1.

$$t=-\frac{I}{I-1}\text{, }t\neq -1$$

Solve for I

$$I=\frac{t}{t+1}$$

$$t\neq -1$$
