Best answer

(a) 3n - 2 = 46

Step I: 3n - 2 + 2 = 46 + 2 [Adding 2 both sides]

⇒ 3n = 48

Step II: 3n/3 =48/3 [Dividing both sides by 3]

⇒ n =16

(b) 5m + 7 = 17

Step I: 5m + 7 - 7 = 17 - 7 [Subtracting 7 both sides]

⇒ 5m = 10

Step II : 5m/5 = 10/5  [Dividing both sides by 5]

⇒ m = 2

(c) 20p/3 = 40

Step I: 20p/3 x 3 = 40 x 3 [Multiplying both sides by 3]

⇒ 20p =120

Step II: 20p /20 = 120/20

⇒ p = 6

(d)  3p/10 = 6 

Step I: 3p/10 x 10 =6 x 10 [Multiplying both sides by 10]

⇒3p = 60

Step II: 3p/3 = 60/3 [Dividing both sides by 3]

⇒ p = 20
