FAQs on Cbse Class 10 Mathematics Chapter 3 Important Questions - Pair of Linear Equations in Two Variables
Below are some of the frequently asked question on the topic Pair of Linear Equations in Two Variables class 10 science:
What is a pair of linear equations in two variables?
A pair of linear equations in two variables consists of two linear equations involving the same two variables. For example, 3z + 4y = 5 and 2x - 3y = 7.
How do you solve a pair of linear equations by substitution?
To solve by substitution, solve one equation for one variable, then substitute that value into the other equation to solve for the second variable.
What is the graphical method of solving a pair of linear equations?
In the graphical method, both equations are plotted on the same graph, and the point of intersection gives the solution.
What is the difference between consistent and inconsistent systems of linear equations?
A consistent system has at least one solution, while an inconsistent system has no solution. Inconsistent systems represent parallel lines that never intersect.
What is the elimination method of solving linear equations?
In the elimination method, the equations are manipulated (by multiplying or adding them) to eliminate one variable, making it easier to solve for the other variable
