Question
i=\frac{u}{z}
Solve the equation
\left(u,z\right) = \left(0,0\right)
Evaluate
i=\frac{u}{z}
Swap the sides of the equation
\frac{u}{z}=i
Cross multiply
u=zi
Simplify the equation
u=iz
Move the expression to the left side
u-iz=0
Rewrite the expression
u+(-z)i=0
Rewrite the expression
\left\{ \begin{array}{l}u=0\\-z=0\end{array}\right.
Change the signs on both sides of the equation
\left\{ \begin{array}{l}u=0\\z=0\end{array}\right.
Solution
\left(u,z\right) = \left(0,0\right)
