Example

3(r+2s)=2t-4
a⋅(b-2)=3b
3(r+2s)=2t-4
a⋅(b-2)=3b

Question

$$Z=\underline{3+l}+2-i$$

Answer

l=Z-5+IM

Solution


Simplify  \(3+l+2-\imath \)  to  \(5+l-\imath \).
\[Z=5+l-\imath \]
Subtract \(5\) from both sides.
\[Z-5=l-\imath \]
Add \(\imath \) to both sides.
\[Z-5+\imath =l\]
Switch sides.
\[l=Z-5+\imath \]
