Ex 2.2, 3 Solve the following linear equations. x + 7 โ 8๐ฅ/3=17/6โ5๐ฅ/2x + 7 โ 8๐ฅ/3=17/6โ5๐ฅ/2 (๐(๐ + ๐) โ ๐๐)/๐=(๐๐ โ ๐๐ ร ๐)/๐ (3๐ฅ + 21 โ 8๐ฅ)/3=(17 โ 15๐ฅ)/6 (3๐ฅ โ 8๐ฅ + 21)/3=(17 โ 15๐ฅ)/6 (โ5๐ฅ + 21)/3=(17 โ 15๐ฅ)/6 6 (โ5x + 21) = 3 (17 โ 15x) โ30x + 126 = 51 โ 45x โ30x = โ45x + 51 โ 126 โ30x = โ45x โ 75 โ30x + 45x = โ75 15x = โ 75 x = (โ75)/15 x = โ5 Check:- โด LHS = RHS Hence Verified. L.H.S ๐ฅ+7โ8๐ฅ/3 =โ5+7โ(8 (โ5))/3 =2+40/3 =(6 + 40)/3=46/3 R.H.S 17/6โ5๐ฅ/2 =17/6โ5(โ5)/2=17/6+25/2 =(17 +3(25))/6 =(17 + 75)/6=92/6=46/3
