Question

what will be the value of the expression n + =6 when n= 3​

Answer 1

Answer:

Given, mx−ny=3 when x=5;y=6

=>5m−6n=3 --- (1)

Also, mx−ny=8 when x=6;y=5

=>6m−5n=8 --- (1)

Multiplying equation (1) with 5 we get, 25m−30n=15 ----- equation (3)

Multiplying equation (2) with 6 we get, 36m−30n=48 ----- equation (4)

Subtracting equation (3)

from (4), we get 11m=33=>m=3

Substituting

m=3 in the equation (1), we get 5(3)−6n=3=>n=2
