Q.3 Give the steps you will use to separate the variables and then solve the equation:
(a) 3n – 2 = 46
(b) 5m + 7 = 17
(c) 20p/3=40
(d) 3p/10=6

Answer :

(a) 3n-2 =46
Or, 3n = 46+2
Or, n = 48/3 = 16
(b) 5m +7 = 17
Or, 5m = 17 -7
Or, m = 10/5 = 2
(c) 20p/3 = 40
Or, 20p= 40×3
Or, p= 120 /20 = 6
(d) 3p/10 = 6
Or, 3p = 6×10
Or, p = 60 /3 = 20
