Question

Solve this equation $i x - 4i = 2$

Answer 1

ANSWER

x = 4 - 2i

EXPLANATION

To solve this equation for x, first, we have to add 4i to both sides,

$\begin{gathered} ix-4i+4i=2+4i \\ ix=2+4i \end{gathered}$

And then multiply both sides by i,

$i^2x=2i+4i^2$

Remember that i² = -1,

$-x=2i-4$

Multiply both sides by -1,

$x=4-2i$

Hence, the solution is x = 4 - 2i.
