In 3D matrix if two columns have same values of the coeffici

In 3D matrix, if two columns have same values of the co-efficient. will that come to zeroed value of one or two of the equations?

Solution

Even If two columns have same values of co-efficient that doesnt necessaryly mean that we can get zeroed values because When we try solve linear equations we apply methods which primaryly perform row operations instead of column operations, So when we try to solve 3D matrix in gauss elimnation or gauss jordan or invertion method, same values in columns play very less pivotal role. Therefore its not neccesary condition that we will get zeroed values if Columns elements are equal.
