Q2 of 59 Page 73

5m-n=3m+4n, then find the values of the following expressions.

i. ii.

(i) Given: 5m – n = 3m + 4m


5m – 3m = 4n + n


2m = 5n


m/n = 5/2


m2/n2 = 25/4


Apply componendo and dividendo:




= 29:21


(ii)


Given: 5m – n = 3m + 4m


5m – 3m = 4n + n


2m = 5n


m/n = 5/2


3m/4n = 15/8


Apply componendo and dividendo:




= 23: 7
