Question

The value of x and y if (3y – 2) + i(7 – 2x) = 0

1 point

(a) x = 7/2, y = 2/3

(b) x = 2/7, y = 2/3

(c) x = 7/2, y = 3/2

(d) x = 2/7, y = 3/2​

Answer 1

Step-by-step explanation:

For a complex number to be 0, both real and imaginary part must be zero

So, 3y-2=0 and 7–2x=0

= 3y=2 and 2x=7

= y=2/3 and x=7/2

For complex x and y

(3y-2) + i (7-2x) =0

= 3y-2+7i-2xi=0

=3y=2xi-7i+2

=y=(2xi-7i+2)/3
