We pick either of the equations and write one variable in terms of the other.

Let us consider the equation 2x+7y=11 and write it as

x=

2

11−7y

...........(1)

Substitute the value of x in Equation 5x+

2

35

y=25 or 5x+17.5y=25. We get

5(

2

11−7y

)+17.5y=25

⇒55−35y+35y=50

⇒50=50

Hence, there is no solution of the given system of equations.
