By exploring two distinct assertions and their underlying reasons, learners will grasp how to analyze pairs of linear equations to determine the nature of their solutions. This video is perfect for Class 10 students aiming to strengthen their understanding of linear equations and prepare for their exams with confidence.

Q1. Assertion: The Linear equation x-2y-3=0 and 3x+4y-20=0 have exactly one solution.
Reason: The linear equation 2x+3y-9=0 and 4x+6y-18=0 have unique solution.
Q2. Assertion: If the lines 3x+2ky-2=0 and 2x+5y+1=0 are parallel, Then the value of k is 15/4.
Reason: The condition for parallel line is a1/a2 = b1/b2 not= c1/c2
