Question

mathematics ughh !!-_- so done wtih this math!

solve the following equations for real X and Y
1) (2-3i) (x+yi) = 4+i

2) (2-2i) (x+yi) = 2(x=2yi) + 2i - 1

need help :( after getting answer i m gonna write this mathematics in my death note lol

Answer 1

come on someone ahh

Answer 2

Btw there are teachers who help us or they are students??

Answer 3

1) (2-3i) (x+yi) = 4+i
is the same as
2(x+yi) -3i(x+iy) = 4 + i

2 x + 2 y i - 3 x i + 3 y = 4 + i
so
2 x + 3 y = 4
2 y - 3 x = 1
then first times 2, second times 3
4 x + 6 y = 8
6 y - 9 x = 3
----------------- subtract
13 x =5
x = 5/13
etc

Answer 4
