Ans 1: (Master Answer)
Class : Class 1
(D): (i) We have, ax + b = 0
⇒ ax = – b
(ii) The shifting of a number from one side of an equation to other is called transposition.
(iii) We have, ax = b
⇒ 
which is the required solution
Given that a and b are positive integers.
∴ Solution of the equation ax = b has to be always positive.
(iv) Linear equation is of the form ax + b = 0 i.e., only one variable with power 1.
