Answer 1

Answer:

2 iv) 2x + i^9y (2+i)=xi^7+10i^16

2x + i^3×i^3×i^3y(2+i)=xi^3×i^4 + 10i^4×i^4×i^4×i^4

2x +(-i)(-i)(-i)y(2+i)=x (-i)×1 + 10×1×1×1×1

2x + iy(2+i)= 10-xi

2x + 2iy + i^2y=10-xi

2x + 2iy -y=10 - xi

2x-y + 2iy =10-xi

(on comparing real and imaginary part)

2x-y =10 (eq.1) 2iy=-xi

2y= -x (eq.2)

(substituting the value of (eq.2) in (eq.1))

2x +x/2= 10

4x+x=20

5x=20

x=4

(putting value of x in (eq.2) to find y)

2y= -x

2y=-4

y=-2
