Question

One equation of the pair of
dependent linear equation is 5 x + 7 Y
equal to 2 then the second can be​

Answer 1

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).
