INTRODUCTION
DEFINE :- A pair of linear equations in two variables is said to form a system of simultaneous linear equations
The general form of pair of linear equations in two variables x and y is :-
a1x + b1y + c1 = 0
a2x + b2y + c2 = 0
METHODS
The Algebraic Methods of solving simultaneous pair Linear Equations in Two Variables are :-
1) METHOD OF ELIMINATION BY SUBSTITUTION
2) METHOD OF ELIMINATION BY EQUATING THE COEFFICIENTS
3) METHOD OF CROSS-MULTIPLICATION
