Question

How do you solve 2x - 2y = 15 and 4x - 4y = 30?

Answer 1

Infinite solutions

Explanation:

Given equations:

`2x-2y=15\ .........(1)` &

`4x-4y=30`

`2x-2y=15\ .........(2)`

Both the above lines are same or they are coincident having infinite number of points of intersection hence the given system equation has infinite solutions.
