Question

x+y i = (1+i) (4-3i)​

Answer 1

Answer:

7+i........here , x=7 and y= 1

Step-by-step explanation:

( 1+i) (4-3i)

= 4 -3i+4i- 3i^2

= 4+i- 3×(-1). [i^2 =-1]

=4+i+3

=7+i

so, x=7 & y=1

Answer 2

Answer:

$x + iy = (1 + i)(4 - 3i) \\ \\ x + iy = 4 - 3i + 4i - 3 {i}^{2} \\ \\ x + iy = 4 + i + 3 \\ \\ x + iy = 7 + i$

comparing both sides we get

$x = 7 \: \: \: and \: \: \: y = 1$
