Answer:

Given equations as :

2

7

x+

2

5

y=5...(1)

4x+2y=7...(2)

From equation (1) we have value of y:

⇒7x+5y=10

⇒5y=10−7x

⇒y=

5

10−7x

Substitute value of y in second equation will have x value:

4x+2(

5

10−7x

)=7

⇒20x+2(10−7x)=35

⇒20x+20−14x=35

⇒6x=15

⇒x=

5

Now replacing x value in equation 2nd will get y value

4(

)+2y=7

⇒20+4y=14

⇒4y=14−20

⇒4y=−6

⇒4y=−6

⇒y=

−6

y=
