Question

if we multiply or divide both sides of a linear equation by a non zero number, then the roots of linear equation will remain same is it true? if so justify with example (say clearly please)

Answer 1

Answer:

multiplying or dividing by a non zero number virtually means that you have not changed the equation by any form

Step-by-step explanation:

suppose

2x+3=25

x=11

multipying and diving both the sides by suppose 'a' where 'a' is a non zero constant

the equation becomes

2ax +3a=25a

if we solve it

2ax=22a

x=11

which is same as the answer above
