If we multiply or divide both sides of a linear equation by a zero number, then the roots of linear equation will remain the same. Is it true? If so justify with an example.

If we multiply or divide both sides of a linear equation by a non zero number, then the roots of linear equation will remain the same. Is it true? If so justify with an example.

A chemical equation which contain the same number of atoms of different eements on reactant side and product side is

If the linear equations ax+by+c=0, (a,b,c!=0) and lx+my+n=0 represent the same line and r=l/a=n/c , write the values of r in the terms m and b.

A lending library has fixed charge for the first three days and an additional charges for each day thereafter. John paid 27 for a book kept for seven days. If the fixed charges be x and subsequent per day charges be y, then write the linear equation representing the above information and draw the graph of the same. From the graph, find fixed charges for the first three if additional charges for each day thereafter is 4. Find additional charges for each day thereafter if the fixed charges for the first three days of 7.
