Answer:
10x−14y=−4
Step-by-step 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).
hope it's helpful to you!
