We can't equate a problem by multiplying 0 on both side because, when We multiply a number on both side, The division of both the number should be equal to 1. For example;. 3x+y=k. If we multiply 0 by both side. 0(3x+y)=0k. Here the division of 0 by 0 is undefined in maths .0/0 is indeterminate means it can't be defined
