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. (v) 4/3 x + 2y = 8 ; 2x + 3y = 12 4/3 x + 2y – 8 = 0 2x + 3y – 12 = 0 𝟒/𝟑 x + 2y – 8 = 0 Comparing with a1x + b1y + c1 = 0 ∴ a1 = 4/3 , b1 = 2 , c1 = –8 2x + 3y – 12 = 0 Comparing with a2x + b2y + c2 = 0 ∴ a2 = 2, b2 = 3, c2 = −12 ∴ a1 = 4/3 , b1 = 2 , c1 = – 8 & a2 = 2, b2 = 3 c2 = −12 Since 𝑎1/𝑎2 = 𝑏1/𝑏2 = 𝑐1/𝑐2 We have infinitely many solutions Therefore, our system is consistent.
