Linear Equations in Two Variables cbse
A linear
equation looks like ax+by+c=0 where x,y are two variables and a, b, c are real
numbers (a≠0 and b ≠0)
Example: 4x
+ 3y -6 = 0
0.3x + 0.4y + 2.8 =0
√2x + √3y = 0
Pair of
Linear Equations in Two Variables:
When two
linear equations are satisfied by the same pair of values of x and y.
Such
as, a₁x +b₁y + c₁
= 0
a₂x + b₂y + c₂ = 0
where a₁,b₁,c₁,a₂,b₂,c₂ are real
numbers and
a₁² + b₁² ≠ 0 a₂² + b₂² ≠ 0
This pair of linear equations can be
solved in two ways:
1. Graphical method
2. Algebric method
