Chapter 3 Class 10 Pair of Linear Equations in Two Variables

Serial order wise

Last updated at June 14, 2023 by Teachoo

Ex 3.1, 3 On comparing the ratios 𝑎1/𝑎2 , 𝑏1/𝑏2 & 𝑐1/𝑐2 , find out whether the following pair of linear equations are consistent, or inconsistent. 3x + 2y = 5 ; 2x – 3y = 7 3x + 2y – 5 = 0 2x – 3y – 7 = 0 3x + 2y – 5 = 0 Comparing with a1x + b1y + c1 = 0 ∴ a1 = 3 , b1 = 2 , c1 = –5 2x – 3y – 7 = 0 Comparing with a2x + b2y + c2 = 0 ∴ a2 = 2 , b2 = –3 , c2 = –7 a1 = 3 , b1 = 2 , c1 = –5 & a2 = 2 , b2 = –3 , c2 = –7 Since 𝑎1/𝑎2 ≠ 𝑏1/𝑏2 We have a unique solution Therefore, our system is consistent.
