Solve Ib=8mA*0.4999=

$$I b = 8 m A \cdot 0.4999 =$$

Solve for A

$$\left\{\begin{matrix}A=\frac{1250Ib}{4999m}\text{, }&m\neq 0\\A\in \mathrm{R}\text{, }&\left(I=0\text{ or }b=0\right)\text{ and }m=0\end{matrix}\right.$$

Steps for Solving Linear Equation

Multiply 8 and 0.4999 to get 3.9992.

$$Ib=3.9992mA$$

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

$$3.9992mA=Ib$$

The equation is in standard form.

$$\frac{4999m}{1250}A=Ib$$

Divide both sides by 3.9992m.

$$\frac{1250\times \frac{4999m}{1250}A}{4999m}=\frac{1250Ib}{4999m}$$

Dividing by 3.9992m undoes the multiplication by 3.9992m.

$$A=\frac{1250Ib}{4999m}$$

Solve for I

$$\left\{\begin{matrix}I=\frac{4999Am}{1250b}\text{, }&b\neq 0\\I\in \mathrm{R}\text{, }&\left(A=0\text{ or }m=0\right)\text{ and }b=0\end{matrix}\right.$$

Steps for Solving Linear Equation

Multiply 8 and 0.4999 to get 3.9992.

$$Ib=3.9992mA$$

The equation is in standard form.

$$bI=\frac{4999Am}{1250}$$

Divide both sides by b.

$$\frac{bI}{b}=\frac{4999Am}{1250b}$$

Dividing by b undoes the multiplication by b.

$$I=\frac{4999Am}{1250b}$$
