Given (x + 2y) + (2x - 3y)i + 4i = 5.

           (x + 2y) + (2x - 3y + 4)i = 5 + 0i

          x + 2y = 5 = >  Then x = 5 - 2y  ----- (1)

          2x - 3y + 4 = 0 = > 2(5 - 2y) - 3y + 4 = 0 

                                         10 - 4y - 3y + 4 = 0

                                           10 - 7y + 4 = 0

                                               - 7y = -14

                                                y = 2.

Substitute y = 2 in (1), we get

x = 5 - 4

   = 1.


The values are x = 1 and y = 2.

Hope this helps!

(x+2y)+(2x-3y)i+4i=5
5 is real part
real part equation
x+2y=5=x=5-2y
imaginary part
2x-3y+4=0
2 (5-2y)-3y=-4
10-4y-3y=-4
-7y=-14
y=2,and x=1
