Question

as the pair of equation x-y=5 and 2y-x=10 in coincident? justify?​

Answer 1

Answer:

The given lines are not coincident

Step-by-step explanation:

Given lines are

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

-x+2y=10..............(2)

Adding (1) and (2), we get

y =15

put y=15 in (1) we get

x-15=5

x=15+5

x=20

The point of intersection is (20, 15)

When solving the equations of the given lines we get a point (20, 15)

$\therefore\:$The given lines are intersecting lines

Hence they are not coincident
