PAIR OF LINEAR EQUATIONS IN TWO VARIABLES
... In this case, the pair of linear equation is dependent and consistent. 6. There are several situations which can be mathematically represented by two equations that are not linear to start with. But we alter them so that they are reduced to a pair of linear equations. EXERCISE 1 1. Aftab tells his d ...
