Ex 2.5, 1 Solve the following linear equations. 𝑥/2−1/5=𝑥/3+1/4 𝑥/2−1/5=𝑥/3+1/4 (5𝑥 − 2)/10=(4𝑥 + 3)/12 12 (5x − 2) = 10 (4x + 3) 60x − 24 = 10 (4x + 3) 60x − 24 = 40x + 30 60x − 40x − 24 = 30 20x − 24 = 30 20x = 30 + 24 20x = 54 x = 54/20 x = 𝟐𝟕/𝟏𝟎 Check:- ∴ LHS = RHS Hence Verified. L.H.S 𝑥/2 −1/5 =27/10 ×1/2−1/5=(27 − 4)/20=23/20 R.H.S 𝑥/3+ 1/4 =27/10×1/3+1/4=(54 + 15)/60=69/60=23/20
