Question

Given that 5 mx + 12 my – 8 nx – 9 ny =0 , find y / 2x in terms of m and n.

Answer

This is a Algebraic Equation question. 

5mx  + 12my – 8nx – 9ny  = 0

x (5m – 8n)  + y (12m – 9n) = 0

x (5m – 8n) = y (9n – 12m)

(5m – 8n) /  3(3n – 4m)  = y/ x

y / 2x = (5m – 8n) / 6(3n – 4m)

5mx + 12my – 8nx – 9ny = 0
12my – 9ny = -5mx + 8nx
3y(4m – 3n) = x(8n – 5m)
y/x = (8n – 5m) / 3(4m – 3n)
y/2x = (8n – 5m) / 6(4m – 3n)

Ans : y/2x = (8n – 5m) / 6(4m – 3n).

5 mx + 12 my – 8 nx – 9 ny =0
5 mx – 8 nx = 9 ny – 12 my
x (5m – 8n) = y (9n – 12m)
2x [(5m – 8n)/2] = y (9n – 12m)
y/2x = (5m-8n)/ (18n – 24m)
