(ii) Which of the following is not a linear equation?
(a) 3x=7 (b) 2m-4/3=1 (c) (x-1)(x+1)=0 (d) y-1=0

Dear student,
Linear equation is an 
algebraic 
equation,
in which the highest 
degree term 
in the variable or variables is of the first 
degree
From the above options, we can see option a, b, d are linear
equations
However, option c when simplified
x-1x+1=0⇒xx+1-1x+1=0⇒x2+x-x-1=0⇒x2-1=0which is quadratic equation
Thus option c is not linear equation
