i. 17p – 2 = 49
∴ 17p – 2 + 2 = 49 + 2 …[Adding 2 on both the sides]
∴ 17p = 51
∴ \(\cfrac{17p}{17}=\cfrac{51}{17}\) …[Dividing both the sides by 17]
ii. 2m + 7 = 9
∴ 2m + 7 – 7 = 9 – 7
…[Subtracting 7 from both the sides]
∴ 2m = 2
\(\therefore \cfrac{2m}{2} =\cfrac{2}{2}\) [Dividing both the sides by 2]
∴ m = 1
