Linear equations are equations where power of the variable is 1.
For example - x2 + x + 1 = 0 is not a linear equation as power of x is 2.
But x + y = 1 is a linear equation as power of x and y is 1.
We will be studying Linear Equations in 2 variables in this chapter
The topics we will be covering in this chapter are,
Check out the topics and excercises below to study and practice Linear Equations for Class 9. We'll be studying a pair of linear equations in Class 10, which involves solving 2 equations instead of 1.
