Question

How do you solve the system of linear equations `y=x+4` and `y-4=x`?

Answer 1

The two equations are the same only written in different ways.

Explanation:

The first one is `y=x+4` and the other one is `y-4=x`

If we transpose the 4 in the second to the right side of the equation, it will be identical with the first equation. These two equations represent the same line.
