Question

Give the steps you will case to separate the variable and then solve the equation:
20P
(i) (3n - 2) = 46
(ii) 5m + 7 = 17
(iii) 20p/3 = 40​

Answer 1

Answer:

i) 3n-2 = 46

3n = 46+2

3n= 48

n= 48/3 = 16

n=16

ii) 5m+ 7= 17

5m= 17-7

5m= 10

m = 10/5 = 2

m=2

iii) 20p/3 = 40

20p = 40×3

20p = 120

p= 120/20 = 6

p=6
