Question

Find real numbers x and y such that
3x + 2iy - ix + 5y = 7 + 5i.

Answer 1

Step-by-step explanation:

Sol: Given 3x + 2iy - ix + 5y = 7 + 5i.

3x + 5y + i( -x + 2y) = 7 + 5i

Comparing real and imaginary part on both sides 3x + 5y = 7 -----------(1) and

-x + 2y = 5 -------------(2)

Solving (1) and (2) we get

x = -1 and y = 2.

Answer 2

Step-by-step explanation:

3x+5y+i(-x +2y)=7 +5i

Both sides --3x +5y= 7 + -x + 2y=5

x= -1

y=2
