Explanation:
Given equation is
−5x+7y=2 -------------(1)
We have to find the dependent equation of above equation
We will check through options
Option A,
= 10x+14y+4=0
= 5x+7y=−2
It cannot be written exactly as eq(1).
So, it is not a dependent equation of (1).
Option B,
= −10x−14y+4=0
= 5x+7y=2
It cannot be written exactly as eq(1).
So, it is not a dependent equation of (1).
Option C,
= −10x+14y+4=0
= −5x+7y=−2
It cannot be written exactly as eq(1).
So, it is not a dependent equation of (1).
Option D,
= 10x−14y=−4
= −5x+7y=2
It is same as (1).
So, it is a dependent equation of (1).
