Find the coordinates of the image of the point P`(1, 3, 4)` in the plane `2x-y+z+3=0`.

Explanation

`ax+by+cz+d=0`

`(x-x_1)/a-(y-y_1)/b=(z-z_1)/c=(-2(ax+by+cz+d)/(a^2+b^2+c^2))`

at point(1,3,4)

`(x-1)/2=(y-3)/(-1)-(z-4)/1=((-2(2*1-3+4+3))/(4+1+1))`

`(x-1)/2=-(y-3)=z-4=(-2(-2))/6=2/3`

`(x-1)/2=2/3`

`x=7/3`

`-(y-3)=2/3`
