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
