9. Determine real numbers x and y for which the following equations are true : (iii) x + 4iy = ix + y ++3​

Answer»

-step explanation:Explanation:x+4iy=ix+y+3 ⇒x−y+4iy−ix=3 ⇒x−y+i(4y−x)=3 We can write 3 as 3+0i ⇒x−y+i(4y−x)=3+0i Equating the REAL and IMAGINARY PARTS...x−y=3 4y−x=0 4y=x ⇒4y−y=3⇒y=1 ⇒x=4 x=4,y=1
