Step-by-step explanation:
An equation which can be put in the form
ax + by + c = 0
where a, b and c are real numbers {a, b ≠ 0) is called a linear equation in two variables ‘x’ and ‘y’
• General Form of a Pair of Linear Equations in Two Variables
General form of a linear pair of equations in two variables is:
a1x + b1y + cx - 0 and
a2x + b2y + c2 = 0
where a1 b1, c1, a2, b2, c2 are real numbers such that
a12 + b12 0 and a22 + b22 0
• Solution of a Pair of Linear Equations in Two Variables
The solution of a linear equation in two variables ‘x’ and ‘y’ is a pair of values (one for ‘x’ and other for ‘y’)
which makes the two sides of the equation equal.
There are two methods to solve a pair of linear equations:
(i) algebraic method
(ii) graphical method.
