The third chapter of CBSE Class 10th Mathematics is ‘Pair of Linear Equations in Two Variables’.
Students will come to know that the equations in which the power of all the variables involved is one are called linear equations. The degree of a linear equation is always one.
The general form of a linear equation in two variables is ax + by + c = 0, where a and b cannot be zero simultaneously.
