You can put this solution on YOUR website! we are given
(i)
step 1 - multiply by the conjugate of (2-i) which is (2+i) to get
(ii)
and simplified, we get
(iii)
we then separate our real and imaginary parts to get
(iv) +
---
at this point there is no equal sign, so we can't solve for x and y, just rewrite using x and y in the real and imaginary parts.
