i can see you are having trouble in understanding the format of the second line
it is nothing but
as 4x-3y+1=0 and 5x-3z+2=0 are equations of plane and intersection of two plane gives a line
how we get the intersection of two plane is completely a different topic and is now releated to this question hence i am not telling you this and you must ask your teacher
hope this will help
