using graph find whether the pair of linear equation 3x-5y=20, 6x-10y+40=0 is consistence or inconsistent. write its solution.
The given set of linear equations are

3x-5y=20...........(1)

6x-10y+40=0 .......(2)

from the graph it is clear that given equations are the equations of the parallel lines.

Hence the given equations  have no solutions.
