Pair of Linear Equations in Two Variables.
Comparing with a2x + b2y + c2 = 0
Learn all Concepts of Chapter 3 Class 10 (with VIDEOS). ∴ a1 = 1 , b1 = –1 , c1 = –8
∴ a2 = 4 , b2 = –4 , c2 = –5
Since 1/2 = 1/2 = 1/2
∴ a1 = 1 , b1 = 1 , c1 = –5
i.e. 4x − 2(0) = 4
So, x = 0, y = −2 is a solution
So, x = 0, y = 5 is a solution
So, x = 5, y = 0 is a solution
(0, 5) is a solution
Comparing with a2x + b2y + c2 = 0
Check - Linear Equations in 2 Variables - Class 10, Ex 3.2, 4
If we do not get a solution, then the pair of linear equations in two variables is called inconsistent equations.

In mathematics and in particularly in algebra, a linear or nonlinear system of equations is called as consistent if there is at least one set of values for the unknowns that satisfies each equation in the system - that is, that when substituted into each of the equations makes each equation hold true as an identity. Therefore, our system is inconsistent
Comparing with a1x + b1y + c1 = 0
0 + y = 5
i.e. Putting x = 0
Now we solve our equations graphically
Show that the equations x + y = 5, 2x + y = 8 are consistent and solve them. x – y = 8
1/2 = (−1)/2

Question 4 - CBSE Class 10 Sample Paper for 2021 Boards - Maths Basic Last updated at Oct. 21, 2020 by Teachoo On comparing the ratios of the coefficients, find out whether the pair of equations x – 2y = 0 and 3x + 4y – 20 = 0 is consistent or inconsistent. (5, 0) is a solution
(i) x + y = 5, 2x + 2y = 10 /
So a consistent system of equations.
For Equation (1)
1/2 = 2/4
a2 = 4 , b2 = –4 , c2 = –5
This video talks about the topic consistent and inconsistent equations from the CBSE Class 10th Mathematics chapter- Pair of Linear Equations in two Variables.
So, (2, 2) is the solution

Table for equation 2x + y – 6 = Table for equation 4x – 2y – 4 = 0 (iv) 2x – 2y – 2 = 0, 4x – 4y – 5 = 0 ∴ Pair of equations is inconsistent. 1/2 = (−1)/(−3)
2x – 2y – 4 = 0
Ex 3.2, 4
1/2 = 1/2
∴ a2 = 2 , b2 = 2 , c2 = –10
In such a case, the pair of linear equations is said to be consistent. This video talks about the topic consistent and inconsistent equations for the chapter Pair of Linear Equations in two Variables. (i) x + y = 14. x – y = 4. x + y – 5 = 0
Hence, this pair of linear equations is consistent. Hence, this pair of linear equations is consistent. 1/2 = 3/2
