Master Class 10th Maths Chapter 3: Pair of Linear Equations in Two Variables. Whether you are struggling with complex Word Problems or confused between Elimination and Substitution methods, this video provides a step-by-step roadmap to score full marks in your Class 10 Boards. [Key Concepts Breakdown] In this session, we cover the core pillars of Linear Equations: โข Graphical Method: Understanding Intersecting, Parallel, and Coincident lines. โข Consistency: How to tell if a system has a Unique Solution, No Solution, or Infinitely Many Solutions using coefficients. โข Algebraic Methods: 1. Substitution Method (The 'replace' technique) 2. Elimination Method (The 'cutting' technique - most popular!) โข Word Problems: Age-related, Speed-Distance, and Fraction-based problems solved with easy tricks.

Hence find the value of โ๐โ for which ๐ฆ = ๐๐ฅ + 3. 01:15:04 Q.19 Determine graphically whether the pair of linear equations 3๐ฅ โ ๐ฆ = 3 and 2๐ฅ โ 3๐ฆ = 2 is consistent or inconsistence. 01:25:01 Q.20 Solve for ๐ฅ and ๐ฆ: ๐๐ฅ + ๐๐ฆ = ๐ and ๐๐ฅ + ๐๐ฆ = 1 + ๐. 01:35:31 Q.21 Find the coordinates of the vertices of the triangle formed by the lines ๐ฆ = ๐ฅ, ๐ฆ = 0, and ๐ฅ + ๐ฆ = 4. 01:41:31 Q.22 Solve for ๐ฅ and ๐ฆ: 47๐ฅ + 31๐ฆ = 63 and 31๐ฅ + 47๐ฆ = 15. 01:47:19 Q.23 The sum of the numerator and the denominator of a fraction is 12. If the denominator is increased by 3, the fraction becomes 1/2. Find the fraction. 01:51:03 Q.24 Five years ago, Nuri was thrice as old as Sonu. Ten years later, Nuri will be twice as old as Sonu. How old are Nuri and Sonu? 01:58:52 Q.25 The sum of the digits of a two โ digit number is 9. Also, nine times this number is twice the number obtained by reversing the order of the digits. Find the number. 02:08:05 Q.26 A boat goes 30 km upstream and 44 km downstream in 10 hours. In 13 hours, it can go 40 km upstream and 55 km downstream. Determine the speed of the stream and the boat in still water. 02:21:29 Q.27 A part of monthly hostel charges is fixed and the remaining depends on the number of days one has taken food in the mess. A student A takes food for 20 days and pays โน1000 as hostel charges. Student B takes food for 26 days and pays โน1180. Find the fixed charges and the cost of food per day. 02:27:53 Q.28 Case Study 01 02:34:10 Q.29 Case Study 02 02:41:50 Q.30 Case Study 03 #MathsByAmanVerma #Class10Maths #LinearEquations #Chapter3Maths #CBSE2026 #MathsOneShot #SubstitutionMethod #EliminationMethod #ImportantQuestions #MathsTricks
